- away your freedom to share and change it. By contrast, the GNU General
- Public License is intended to guarantee your freedom to share and change
- free software--to make sure the software is free for all its users.
-This General Public License applies to most of the Free Software Foundation's
- software and to any other program whose authors commit to using it.
-(Some other Free Software Foundation software is covered by the GNU Library
- General Public License instead.) You can apply it to your programs, too.
- </p>
-
-<div align="justify"> </div>
-
-<p align="justify"> When we speak of free software, we are referring to
- freedom, not price. Our General Public Licenses are designed to make
- sure that you have the freedom to distribute copies of free software
-(and charge for this service if you wish), that you receive source code
-or can get it if you want it, that you can change the software or use pieces
- of it in new free programs; and that you know you can do these things. </p>
-
-<div align="justify"> </div>
-
-<p align="justify"> To protect your rights, we need to make restrictions
- that forbid anyone to deny you these rights or to ask you to surrender
- the rights. These restrictions translate to certain responsibilities
-for you if you distribute copies of the software, or if you modify it.
- </p>
-
-<div align="justify"> </div>
-
-<p align="justify"> For example, if you distribute copies of such a program,
- whether gratis or for a fee, you must give the recipients all the rights
- that you have. You must make sure that they, too, receive or can get
- the source code. And you must show them these terms so they know their
- rights. </p>

-<div align="justify"> </div>
-

-<p align="justify"> Finally, any free program is threatened constantly by

- or other work which contains a notice placed by the copyright holder
- saying it may be distributed under the terms of this General Public License.
- The "Program", below, refers to any such program or work, and a "work
- based on the Program" means either the Program or any derivative work
-under copyright law: that is to say, a work containing the Program or
-a portion of it, either verbatim or with modifications and/or translated
-into another language. (Hereinafter, translation is included without limitation
-in the term "modification".) Each licensee is addressed as "you". </p>
-
-<p align="justify"> Activities other than copying, distribution and modification
- are not covered by this License; they are outside its scope. The act
- of running the Program is not restricted, and the output from the Program
- is covered only if its contents constitute a work based on the Program
- (independent of having been made by running the Program). Whether that
- is true depends on what the Program does. </p>
-
-<p align="justify"> <strong>1.</strong> You may copy and distribute verbatim
- copies of the Program's source code as you receive it, in any medium,
- provided that you conspicuously and appropriately publish on each copy
- an appropriate copyright notice and disclaimer of warranty; keep intact
- all the notices that refer to this License and to the absence of any
-warranty; and give any other recipients of the Program a copy of this License
-along with the Program. </p>
-
-<p align="justify"> You may charge a fee for the physical act of transferring
- a copy, and you may at your option offer warranty protection in exchange
- for a fee. </p>
-
-<p align="justify"> <strong>2.</strong> You may modify your copy or copies
- of the Program or any portion of it, thus forming a work based on the
- Program, and copy and distribute such modifications or work under the
- terms of Section 1 above, provided that you also meet all of these conditions:

+
+<p>Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/></p><p>
+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.</p>
+
+<h3><a name="preamble"></a>Preamble</h3>
+
+<p>The GNU General Public License is a free, copyleft license for
+software and other kinds of works.</p>
+
+<p>The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.</p>
+
+<p>When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.</p>
+
+<p>To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.</p>
+
+<p>For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.</p>
+
+<p>Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.</p>
+
+<p>For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.</p>
+
+<p>Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.</p>
+
+<p>Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.</p>
+
+<p>The precise terms and conditions for copying, distribution and
+modification follow.</p>
+
+<h3><a name="terms"></a>TERMS AND CONDITIONS</h3>
+
+<h4><a name="section0"></a>0. Definitions.</h4>
+
+<p>“This License” refers to version 3 of the GNU General Public License.</p>
+
+<p>“Copyright” also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.</p>
+
+
+<p>“The Program” refers to any copyrightable work licensed under this
+License. Each licensee is addressed as “you”. “Licensees” and
+“recipients” may be individuals or organizations.</p>
+
+<p>To “modify” a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a “modified version” of the
+earlier work or a work “based on” the earlier work.</p>
+
+<p>A “covered work” means either the unmodified Program or a work based
+on the Program.</p>
+
+<p>To “propagate” a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.</p>
+
+<p>To “convey” a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.</p>
+
+<p>An interactive user interface displays “Appropriate Legal Notices”
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.</p>
+
+<h4><a name="section1"></a>1. Source Code.</h4>
+
+<p>The “source code” for a work means the preferred form of the work
+for making modifications to it. “Object code” means any non-source
+form of a work.</p>
+
+<p>A “Standard Interface” means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.</p>
+
+<p>The “System Libraries” of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+“Major Component”, in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.</p>
+
+<p>The “Corresponding Source” for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.</p>
+
+<p>The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.</p>
+
+<p>The Corresponding Source for a work in source code form is that
+same work.</p>
+
+<h4><a name="section2"></a>2. Basic Permissions.</h4>
+
+<p>All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.</p>
+
+<p>You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.</p>
+
+<p>Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.</p>
+
+<h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4>
+
+<p>No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.</p>
+
+<p>When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.</p>
+
+<h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4>
+
+<p>You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.</p>
+
+<p>You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.</p>
+
+<h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4>
+
+<p>You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:</p>
+
<ul>
- <li><strong>a)</strong> You must cause the modified files
- to carry prominent notices stating that you changed the files and
- the date of any change.
-
- <p> </p>
- </li>
- <li><strong>b)</strong> You must cause any work that
-you distribute or publish, that in whole or in part contains or
-is derived from the Program or any part thereof, to be licensed
-as a whole at no charge to all third parties under the terms of this
-License.
-
- <p> </p>
- </li>
- <li><strong>c)</strong> If the modified program normally
- reads commands interactively when run, you must cause it, when
-started running for such interactive use in the most ordinary way,
-to print or display an announcement including an appropriate copyright
-notice and a notice that there is no warranty (or else, saying that
-you provide a warranty) and that users may redistribute the program
-under these conditions, and telling the user how to view a copy of
-this License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.) </li>
-
+<li>a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.</li>
+
+<li>b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ “keep intact all notices”.</li>
+
+<li>c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.</li>
+
+<li>d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.</li>
</ul>
- These requirements apply to the modified work as a whole.
- If identifiable sections of that work are not derived from the Program,
- and can be reasonably considered independent and separate works in themselves,
- then this License, and its terms, do not apply to those sections when
- you distribute them as separate works. But when you distribute the
-same sections as part of a whole which is a work based on the Program,
-the distribution of the whole must be on the terms of this License, whose
-permissions for other licensees extend to the entire whole, and thus
-to each and every part regardless of who wrote it. </div>
-
-<p align="justify"> Thus, it is not the intent of this section to claim rights
-or contest your rights to work written entirely by you; rather, the intent
-is to exercise the right to control the distribution of derivative or collective
-works based on the Program. </p>
-
-<p align="justify"> In addition, mere aggregation of another work not based
- on the Program with the Program (or with a work based on the Program)
- on a volume of a storage or distribution medium does not bring the other
- work under the scope of this License. </p>
-
-<p align="justify"> <strong>3.</strong> You may copy and distribute the
- Program (or a work based on it, under Section 2) in object code or executable
- form under the terms of Sections 1 and 2 above provided that you also
- do one of the following: <!-- we use this doubled UL to get the sub-sections indented, -->
- <!-- while making the bullets as unobvious as possible. --> </p>
-
-<div align="justify">
+
+<p>A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+“aggregate” if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.</p>
+
+<h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4>
+
+<p>You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:</p>
+
<ul>
- <li><strong>a)</strong> Accompany it with the complete
- corresponding machine-readable source code, which must be distributed
- under the terms of Sections 1 and 2 above on a medium customarily
- used for software interchange; or,
-
- <p> </p>
- </li>
- <li><strong>b)</strong> Accompany it with a written offer,
- valid for at least three years, to give any third party, for a
-charge no more than your cost of physically performing source distribution,
- a complete machine-readable copy of the corresponding source code,
- to be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange; or,
-
- <p> </p>
- </li>
- <li><strong>c)</strong> Accompany it with the information
- you received as to the offer to distribute corresponding source
- code. (This alternative is allowed only for noncommercial distribution
- and only if you received the program in object code or executable
-form with such an offer, in accord with Subsection b above.) </li>
-
+<li>a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.</li>
+
+<li>b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.</li>
+
+<li>c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.</li>
+
+<li>d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.</li>
+
+<li>e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.</li>
</ul>
- The source code for a work means the preferred form of the
-work for making modifications to it. For an executable work, complete
-source code means all the source code for all modules it contains, plus
-any associated interface definition files, plus the scripts used to control
-compilation and installation of the executable. However, as a special
-exception, the source code distributed need not include anything that
-is normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on which
-the executable runs, unless that component itself accompanies the executable.
-</div>
-
-<p align="justify"> If distribution of executable or object code is made
- by offering access to copy from a designated place, then offering equivalent
- access to copy the source code from the same place counts as distribution
- of the source code, even though third parties are not compelled to copy
- the source along with the object code. </p>
-
-<p align="justify"> <strong>4.</strong> You may not copy, modify, sublicense,
- or distribute the Program except as expressly provided under this License.
- Any attempt otherwise to copy, modify, sublicense or distribute the
- Program is void, and will automatically terminate your rights under this
- License. However, parties who have received copies, or rights, from
-you under this License will not have their licenses terminated so long
-as such parties remain in full compliance. </p>
-
-<p align="justify"> <strong>5.</strong> You are not required to accept
- this License, since you have not signed it. However, nothing else grants
- you permission to modify or distribute the Program or its derivative
- works. These actions are prohibited by law if you do not accept this
- License. Therefore, by modifying or distributing the Program (or any work
- based on the Program), you indicate your acceptance of this License to
-do so, and all its terms and conditions for copying, distributing or modifying
- the Program or works based on it. </p>
-
-<p align="justify"> <strong>6.</strong> Each time you redistribute the Program
-(or any work based on the Program), the recipient automatically receives a
-license from the original licensor to copy, distribute or modify the Program
- subject to these terms and conditions. You may not impose any further
- restrictions on the recipients' exercise of the rights granted herein.
- You are not responsible for enforcing compliance by third parties to this
- License. </p>
-
-<p align="justify"> <strong>7.</strong> If, as a consequence of a court
- judgment or allegation of patent infringement or for any other reason
- (not limited to patent issues), conditions are imposed on you (whether
- by court order, agreement or otherwise) that contradict the conditions
- of this License, they do not excuse you from the conditions of this License.
- If you cannot distribute so as to satisfy simultaneously your obligations
- under this License and any other pertinent obligations, then as a consequence
- you may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to refrain
-entirely from distribution of the Program. </p>
-
-<p align="justify"> If any portion of this section is held invalid or unenforceable

-
-<p align="justify"> It is not the purpose of this section to induce you to
-infringe any patents or other property right claims or to contest validity
- of any such claims; this section has the sole purpose of protecting
-the integrity of the free software distribution system, which is implemented
- by public license practices. Many people have made generous contributions
- to the wide range of software distributed through that system in reliance
- on consistent application of that system; it is up to the author/donor
- to decide if he or she is willing to distribute software through any other
- system and a licensee cannot impose that choice. </p>

- is believed to be a consequence of the rest of this License. </p>
-
-<p align="justify"> <strong>8.</strong> If the distribution and/or use of

-interfaces, the original copyright holder who places the Program under this
-License may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among countries
-not thus excluded. In such case, this License incorporates the limitation
-as if written in the body of this License. </p>

- number of this License, you may choose any version ever published by

-<h3>END OF TERMS AND CONDITIONS</h3>
- <br>
-
-<hr width="100%" size="2"><br>
-
-<div align="center">
+
+<p>A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.</p>
+
+<p>A “User Product” is either (1) a “consumer product”, which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, “normally used” refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.</p>
+
+<p>“Installation Information” for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.</p>
+
+<p>If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).</p>
+
+<p>The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.</p>
+
+<p>Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.</p>
+
+<h4><a name="section7"></a>7. Additional Terms.</h4>
+
+<p>“Additional permissions” are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.</p>
+
+<p>When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.</p>
+
+<p>Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:</p>
+
+<ul>
+<li>a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or</li>
+
+<li>b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or</li>
+
+<li>c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or</li>
+
+<li>d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or</li>
+
+<li>e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or</li>
+
+<li>f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.</li>
+</ul>
+
+<p>All other non-permissive additional terms are considered “further
+restrictions” within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.</p>
+
+<p>If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.</p>
+
+<p>Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.</p>
+
+<h4><a name="section8"></a>8. Termination.</h4>
+
+<p>You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).</p>
+
+<p>However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.</p>
+
+<p>Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.</p>
+
+<p>Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.</p>
+
+<h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4>
+
+<p>You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.</p>
+
+<h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4>
+
+<p>Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.</p>
+
+<p>An “entity transaction” is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.</p>
+
+<p>You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.</p>
+
+<h4><a name="section11"></a>11. Patents.</h4>
+
+<p>A “contributor” is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's “contributor version”.</p>
+
+<p>A contributor's “essential patent claims” are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, “control” includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.</p>
+
+<p>Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.</p>
+
+<p>In the following three paragraphs, a “patent license” is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To “grant” such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.</p>
+
+<p>If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. “Knowingly relying” means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.</p>
+
+
+<p>If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.</p>
+
+<p>A patent license is “discriminatory” if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.</p>
+
+<p>Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.</p>
+
+<h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4>
+
+<p>If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.</p>
+
+<h4><a name="section13"></a>13. Use with the GNU Affero General Public License.</h4>
+
+<p>Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.</p>
+
+<h4><a name="section14"></a>14. Revised Versions of this License.</h4>
+
+<p>The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.</p>
+
+<p>Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License “or any later version” applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.</p>
+
+<p>If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.</p>
+
+<p>Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.</p>
+
+<h4><a name="section15"></a>15. Disclaimer of Warranty.</h4>
+
+<p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p>
+
+<h4><a name="section16"></a>16. Limitation of Liability.</h4>
+
+<p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.</p>
+
+<h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4>
+
+<p>If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.</p>

<h3><a name="Everything_in_its_place..."></a>Everything in its place...</h3>
-
-<p>Hopefully you've unpacked the distribution archive into its own directory.
- This is the directory in which all Citadel files are located and in
-which all activity will take place. Several subdirectories have already
-been created during the unpacking process, and others may be created
-by the software if needed. Make sure you have Berkeley DB installed on
-your system, and that you have all the development libraries and headers
-in place so that you can compile against them. If you don't, you can
-get the latest Berkeley DB at <a href="http://www.sleepycat.com">http://www.sleepycat.com</a>.
- If your operating system uses a separate library to support POSIX threads
- (pthreads), make sure that library is installed as well. This is almost
- never the case with Linux, but some commercial Unix flavors might need
- it.</p>
-
-<h3><a name="The_BBS_Login"></a></h3>
-
-<h3>The BBS Login</h3>
-
-<p>As with many Unix programs, Citadel wants to run under its own user ID.
- Unlike other programs, however, this user ID will do double-duty as a
-public login for your system if you are running a BBS. This account is
-typically called "bbs" or "citadel" or something to that effect. You will
-tell Citadel what the user-id of that account is, and when someone logs
-in under that account, Citadel will prompt for a user name.</p>
-
-<p>The Citadel user should have a unique uid. The home directory should be
- the one your Citadel installation resides in (in this example we will
-use /usr/local/citadel) and the shell should be either "citadel" in that
-directory, or a script that will start up citadel (you may wish to set
-up an external text editor; see below). Example:</p>
-
-<pre>bbs::100:1:BBS Login:/usr/local/citadel:/usr/local/citadel/citadel<br></pre>
-
-<p>When you run setup later, you will be required to tell it what the Citadel
- user's numeric user ID is, so it knows what user to run as. If you create
- an account called <tt>bbs</tt>, <tt>guest</tt>, or <tt>citadel</tt>, the
- setup program will automatically pick up the user ID by default.</p>
-
-<p>For all other users in /etc/passwd, Citadel will automatically set up
-an account using the full name (or 'gecos' in Unixspeak) of the user. It'll
- also ignore any password you supply, because it uses the user's password
- on the host system. This allows a 'single sign on' type of environment.
- Note that this does have to be enabled at compile time -- it's the configure
- option called <tt>--enable-autologin</tt>. Keep in mind that these users
- can use *either* their Citadel login name or their login name on the host
- computer, and their password on the host computer.</p>
-
-<h3><a name="Bypassing_the_login:_prompt"></a></h3>
-
-<h3>Bypassing the <tt>login:</tt> prompt</h3>
-
-<p>If you normally log in to your host system using some method other than
- telnet (such as ssh), you might want the telnet service to go straight
- to the Citadel BBS, instead of displaying the <tt>login:</tt> prompt first.
- You can do this by having telnetd start citadel directly instead of
-<tt>/bin/login</tt>. This is actually very simple to implement; all you
-need to do is make a simple change to your <tt>inetd</tt> or <tt>xinetd</tt>
-configuration. Here are some configuration examples.</p>
-
-<p>An example for <tt>inetd</tt> (put the following line in <tt>/etc/inetd.conf</tt>,
- replacing any existing telnet configuration line already there):</p>

+directory. This is the directory in which all Citadel files are located
+and in
+which all activity will take place. Several subdirectories have already
+been created during the unpacking process, and others may be created
+by the software if needed. Make sure you have Berkeley DB installed on

+threads (pthreads), make sure that library is installed as well. This
+is almost never the case with Linux, but some commercial Unix flavors

+<h3><a name="ctdl_login_acct"></a>Creating a system account for Citadel</h3>
+<p>As with many Unix programs, Citadel wants to run under its own user
+ID. Unlike other programs, however, this user ID will do double-duty as
+a public login for your system if you are running a BBS. This account
+is typically called "bbs" or "citadel" or something to that effect. You
+will tell Citadel what the user-id of that account is, and when someone
+logs in under that account, Citadel will prompt for a user name.</p>
+<p>The Citadel user should have a unique uid. The home directory should
+be the one your Citadel installation resides in (in this example we
+will use <tt>/usr/local/citadel</tt>) and the shell should be either
+"citadel" in
+that directory, or a script that will start up the citadel client.
+Example:</p>
+<pre>citadel::100:1:Citadel Login:/usr/local/citadel:/usr/local/citadel/citadel<br></pre>
+<p>When you run setup later, you will be required to tell it the
+username or user ID of the account you created is, so it knows what
+user to run as. If you create an account called <tt>citadel, bbs</tt>,
+or <tt>guest</tt>, the setup program will automatically pick up the
+user ID by default.</p>
+<p>For all other users in <tt>/etc/passwd</tt> (or in some other name
+service such as NIS), Citadel can automatically set up
+such as NIS), Citadel can automatically set up
+an account using the full name (or 'gecos' in Unixspeak) of the user.
+It'll also ignore any password you supply, because it uses the user's
+password on the host system. This allows a 'single sign on' type of
+environment.
+Note that this does have to be enabled at setup time -- it's the
+option called "host based authentication mode". Keep in
+mind that these users can use *either* their Citadel login name or
+their login name on the host computer, and their password on the
+host computer.</p>

+configure
+this automatically for you if it sees a configuration it understands.
+If you would prefer to configure it manually, all you need to do is
+make a
+simple change to your <tt>inetd</tt> or <tt>xinetd</tt>
+configuration. Here are some configuration examples.</p>

<p>So if you did this:</p>
-
-<pre>printcmd="nl|pr|lpr -Plocal"<br></pre>
-
-<p>...that would add line numbers, then paginate, then print on the printer
- named "local". There's tons of stuff you can do with this feature. For
- example, you could use a command like <tt>cat <<$HOME/archive</tt>
- to save copies of important messages in a textfile. Again, this is probably
- something you don't want to configure for a public BBS host -- most system
- administrators don't want remote users sending arbitrary things to local
- printers.</p>
-
+<pre>printcmd="a2ps -o - |lpr -Plocal"<br></pre>
+<p>...that would convert the printed text to PostScript, then print on

+<li><i>Native authentication</i> - Citadel maintains its own user database.

+host server.
+<li><i>Host based authentication</i> - access to Citadel is authenticated
+against the user database (<tt>/etc/passwd</tt> or perhaps NIS, etc.).

<p>The options are as follows:</p>
-
-<p><tt>-hHomeDir</tt> - the directory your BBS data files live in. This should,

-
+<p><tt>-xDebugLevel</tt> - Set the verbosity of trace messages printed.
+When -x is used, it will suppress messages sent to syslog (see below).

-installations; if you are using Berkeley DB it has no effect.)</p>
-
-<p>The preferred method of starting the Citadel server is to place an entry
- in your /etc/inittab file. This will conveniently bring the server up
-when your system is up, and terminate it gracefully when your system is
-shutting down. The exact syntax for your system may vary, but here's an

<p>The next set of options affect how Citadel behaves on a network.</p>
-
-<pre>
-How often to run network jobs (in seconds) [3600]: <br>
-POP3 server port (-1 to disable) [110]:<br>
-IMAP server port (-1 to disable) [143]:<br>
-SMTP server port (-1 to disable) [25]: <br>
-Correct forged From: lines during authenticated SMTP [Yes]:<br>
-</pre>
-
-<p>'How often to run network jobs' refers to the sharing of content on a
-Citadel network. If your system is on a Citadel network, this configuration
-item dictates how often the Citadel server will contact other Citadel servers
-to send and receive messages. In reality, this will happen more frequently
-than you specify, because other Citadel servers will be contacting yours
-at regular intervals as well.</p>
-
-<p>Then you can specify TCP port numbers for the SMTP, POP3, and IMAP services.
-For a system being used primarily for Internet e-mail, these are essential,
-so you'll want to specify the standard port numbers: 25, 110, and 143.
-If Citadel is running alongside some other mail system, though, then you
-might want to choose other, unused port numbers, or enter -1 for any protocol
+<pre>Server IP address (0.0.0.0 for 'any') [0.0.0.0]:<br>POP3 server port (-1 to disable) [110]:<br>POP3S server port (-1 to disable) [995]:<br>IMAP server port (-1 to disable) [143]:<br>IMAPS server port (-1 to disable) [993]:<br>SMTP MTA server port (-1 to disable) [25]:<br>SMTP MSA server port (-1 to disable) [587]:<br>SMTPS server port (-1 to disable) [465]:<br>Correct forged From: lines during authenticated SMTP [Yes]:<br>Allow unauthenticated SMTP clients to spoof my domains [No]: No<br>Instantly expunge deleted IMAP messages [No]: Yes<br></pre>
+<p>"Server IP address" refers to the IP address on <span
+ style="font-style: italic;">your server</span> to which Citadel's
+protocol services should be bound. Normally you will leave this
+set to 0.0.0.0, which will cause Citadel to listen on all of your
+server's interfaces. However, if you are running multiple
+Citadels on a server with multiple IP addresses, this is where you
+would specify which one to bind this instance of Citadel to.</p>
+<p>Then you can specify TCP port numbers for the SMTP, POP3, and IMAP
+services. For a system being used primarily for Internet e-mail, these
+are essential, so you'll want to specify the standard port numbers: 25,
+110, and 143. If Citadel is running alongside some other mail system,
+though, then you might want to choose other, unused port numbers, or
+enter -1 for any protocol
to disable it entirely.</p>
-
+<p>You'll also notice that you can specify two port numbers for SMTP:
+one
+for MTA (Mail Transport Agent) and one for MSA (Mail Submission Agent).
+The
+traditional ports to use for these purposes are 25 and 587. If you are
+running an external MTA, such as Postfix (which submits mail to Citadel
+using
+LMTP) or Sendmail (which submits mail to Citadel using the 'citmail'
+delivery agent), that external MTA will be running on port 25, and you
+should
+specify "-1" for the Citadel MTA port to disable it. The MSA port
+(again,
+usually 587) would be the port used by end-user mail client programs
+such as
+Aethera, Thunderbird, Eudora, or Outlook, to submit mail into the
+system.
+All connections to the MSA port <b>must</b> use Authenticated SMTP.<br>
+</p>
+<p>The protocols ending in "S" (POP3S, IMAPS, and SMTPS) are
+SSL-encrypted. Although all of these protocols support the
+STARTTLS command, older client software sometimes requires connecting
+to "always encrypted" server ports. Usually when you are looking
+at a client program that gives you a choice of "SSL or TLS," the SSL
+option will connect to one of these dedicated ports, while the TLS
+option will connect to the unencrypted port and then issue a STARTTLS
+command to begin encryption. (It is worth noting that this is <span
+ style="font-style: italic;">not</span> the proper use of the acronyms
+SSL and TLS, but that's how they're usually used in many client
+programs.)<br>
+</p>
+<p>All of the default port numbers, including the encrypted ones, are
+the standard ones.<br>
+</p>
<p>The question about correcting forged From: lines affects how Citadel
-behaves with authenticated SMTP clients. Citadel does not ever allow
+behaves with authenticated SMTP clients. Citadel does not ever allow
third-party SMTP relaying from unauthenticated clients -- any incoming
-messages must be addressed to a user on the system or somewhere in a Citadel
-network. To use Citadel with SMTP client software such as Netscape, Outlook,
-Eudora, or whatever, users must log in with a username and password. In order
-to prevent message forgeries, Citadel discards the <TT>From:</TT> line in any
-message entered by an authenticated user, and replaces it with a
-<TT>From:</TT> line containing the user's genuine name and e-mail address.
-Technically, this violates RFC822, because headers are never supposed to be
-altered, but common sense dictates that this is a good idea. Nevertheless,
-if you want to suppress this behavior, answer 'No' at the prompt (the default
-is 'Yes') and the headers will never be altered.</p>
-
-<p>The final set of options configures system-wide defaults for the auto-purger:</p>
-
-<pre>Default user purge time (days) [120]: <br>Default room purge time (days) [30]: <br>System default message expire policy (? for list) [2]: <br>Keep how many messages online? [150]:<br></pre>
-
-<p>Any user who does not log in for the period specified in 'Default user
- purge time' will be deleted the next time a purge is run. This setting
- may be modified on a per-user basis.</p>
-
-<p>'Default room purge time' behaves the same way, and may also be modified
- on a per-room basis.</p>
-
-<p>'System default message expire policy' defines the way in which old messages
- are expired (purged) off the system. You can specify any of:</p>
-
+messages must be
+addressed to a user on the system or somewhere in a Citadel network. To
+use Citadel with SMTP client software such as Netscape, Outlook,

+whatever, users must log in with a username and password. In order to

+common
+sense dictates that this is a good idea. Nevertheless, if you want to
+suppress
+this behavior, answer 'No' at the prompt (the default is 'Yes') and the
+headers
+will never be altered.</p>
+<p>"Instant expunge" affects what happens when IMAP users delete
+messages. As you may already know, messages are not <i>truly</i> deleted
+when an IMAP client sends a delete command; they are only <i>marked for
+deletion</i>. The IMAP client must also send an "expunge" command
+to actually delete the message. The Citadel server automatically expunges
+messages when the client logs out or selects a different folder, but if you
+select the Instant Expunge option, an expunge operation will automatically
+follow any delete operation (and the client will be notified, preventing any
+mailbox state problems). This is a good option to select, for example, if you
+have users who leave their IMAP client software open all the time and are
+wondering why their deleted messages show up again when they log in from a
+different location (such as WebCit).</p>
+<p>"Allow spoofing" refers to the security level applied to
+non-authenticated SMTP clients. Normally, when another host connects to
+Citadel via SMTP to deliver mail, Citadel will reject any attempt to send
+mail whose sender (From) address matches one of your host's own domains. This
+forces your legitimate users to authenticate properly, and prevents foreign
+hosts (such as spammers) from forging mail from your domains. If, however,
+this behavior is creating a problem for you, you can select this option to
+bypass this particular security check.<br>

+Connect this Citadel to an LDAP directory [No]: No</span><br>
+</p>
+<p>The LDAP configuration options are discussed elsewhere in this

+<p>The final set of options configures system-wide defaults for the

+setting may be modified on a per-user basis.</p>
+<p>'Default room purge time' behaves the same way, and may also be
+modified on a per-room basis.</p>
+<p>'System default message expire policy' defines the way in which old
+messages are expired (purged) off the system. You can specify any of:</p>
<ul>
- <li>Purge by age (specify in days) </li>
- <li>Purge by message count in the room (specify number of messages)

+hour you specify. If your site is much busier at night than
+during the day, you may choose to have the auto-purger run during the
+day.</p>
+<p>"Enable full text search index," if enabled, instructs the server to
+build and maintain a searchable index of all messages on the
+system. This is a time and resource intensive process -- it could
+take days to build the index if you enable it on a large
+database. It is also fairly memory intensive; we do not recommend
+that you enable the index unless your host system has at least 512 MB
+of memory. Once enabled, however, it will be updated
+incrementally
+and will not have any noticeable impact on the interactive response
+time of your system. The full text index is currently only
+searchable when using IMAP clients; other search facilities will be
+made available in the near future.</p>
+<p>The "Perform journaling..." options allow you to configure
+your Citadel server to send an extra copy of every message, along with
+recipient information if applicable, to the email address of your choice.
+The journaling destination address may be an account on the local Citadel
+server, an account on another Citadel server on your network, or an Internet
+email address. These options, used in conjunction with an archiving service,
+allow you to build an archive of all messages which flow through your Citadel
+system. This is typically used for regulatory compliance in industries which

+<p><b>localhost:</b> Basically what you're doing here is telling
+Citadel
what any aliases for your machine are. If your machine were <tt>schmeep.splorph.com</tt>
- and you also had a DNS entry set up for <tt>blah.com</tt>, you might want
- to enter '1' and enter <tt>blah.com</tt> as your alias, so that e-mail
-sent to that address won't bounce.</p>
-
-<p><i>Important tip:</i> if your system is known by one name and <i>only</i>
- one domain, you might not even need to do this at all. You will recall
-that you entered your system's fully qualified domain name earlier when you
-went through the <tt><b>.A</b>ide <b>S</b>ystem configuration <b>G</b>eneral</tt>
- command. The domain name you entered there is automatically considered
-by Citadel to be a 'localhost' entry in your Internet mail configuration.
- It does not hurt to enter it in both locations, though.</p>
-
-<p><b>gateway domain:</b> this is a simple way of mapping various Citadel
- hosts in an Internet domain. For example, if you enter <tt>bar.com</tt>
- as a gateway domain, then mail to users at <tt>foo.bar.com</tt> will be forwarded
- to the host called <tt>foo</tt> on a Citadel network, mail to users at <tt>kunst.bar.com</tt>
- will be delivered to the Citadel server called <tt>kunst</tt>, etc. This
- feature has limited usefulness; if you are operating a network of Citadel
- servers, it is more likely that you will use the 'directory' feature, explained
- below.</p>

- to its destination. This may not be appropriate for some sites; you may
- require (due to local convention, security policy, or whatever) that all
-outbound mail be sent to an SMTP relay or forwarder. To configure this
-functionality, simply enter the domain name or IP address of your relay
-as a 'smart-host' entry.</p>
-
-<p><b>directory:</b> a domain for which you are participating in directory
- services across any number of Citadel nodes. For example, if users who
-have addresses in the domain <tt>citadel.org</tt> are spread out across multiple
- Citadel servers on your network, then enter <tt>citadel.org</tt> as a 'directory'
-entry. <i>For this to work, all Citadel servers participating in directory
-service <b>must</b> carry and share the <tt>Global Address Book></tt>
- room.</i></p>
-
+and you also had a DNS entry set up for <tt>blah.com</tt>, you might
+want to enter '1' and enter <tt>blah.com</tt> as your alias, so that
+e-mail
+sent to that address won't bounce.</p>
+<p><i>Important tip:</i> if your system is known by one name and <i>only</i>
+one domain, you might not even need to do this at all. You will recall
+that you entered your system's fully qualified domain name earlier when
+you went through the <tt><b>.A</b>ide <b>S</b>ystem configuration <b>G</b>eneral</tt>
+command. The domain name you entered there is automatically considered
+by Citadel to be a 'localhost' entry in your Internet mail
+configuration. It does not hurt to enter it in both locations, though.</p>
+<p><b>gateway domain:</b> this is a simple way of mapping various
+Citadel hosts in an Internet domain. For example, if you enter <tt>bar.com</tt>
+as a gateway domain, then mail to users at <tt>foo.bar.com</tt> will
+be forwarded to the host called <tt>foo</tt> on a Citadel network,
+mail to users
+at <tt>kunst.bar.com</tt> will be delivered to the Citadel server
+called
+<tt>kunst</tt>, etc. This feature has limited usefulness; if you are
+operating
+a network of Citadel servers, it is more likely that you will use the

+<p>If your relay server is running on a port other
+than the standard SMTP port 25, you can also specify the port number
+using "host:port" syntax; i.e. <tt>relay99.myisp.com:2525</tt></p>
+<p>Furthermore, if your relay server requires authentication, you can
+specify it using username:password@host or username:password@host:port
+syntax; i.e. <tt>jsmith:pass123@relay99.myisp.com:25</tt></p>
+<p><b>directory:</b> a domain for which you are participating in

<p><b>spamassassin:</b> if you are running a <a

-<b>local</b> network, enter its name or IP address as a 'spamassassin' entry.
- This may be (and, in fact, will usually be) <tt>127.0.0.1</tt> to specify

- is always running on your computer. Citadel does not utilize the <tt>spamc</tt>
- client; instead, it implements SpamAssassin's protocol on its own.</p>
-
-<p>Connecting to a SpamAssassin service across a wide area network is strongly

- Doing this over a wide area network would consume time and bandwidth, which
-would affect performance.</p>
-
-<p>Citadel invokes the SpamAssassin service when incoming messages are arriving
- via SMTP. Before a message is accepted, it is submitted to SpamAssassin.
- If SpamAssassin determines that the message is spam, the Citadel SMTP
-service <i>rejects the message,</i> causing a delivery failure on the sending

<p><b>RBL:</b> Realtime Blackhole Lists (RBL's) provide defense against

-
-<p>Citadel can utilize any RBL that uses the
-<tt>z.y.x.w.nameoflist.org</tt> syntax, where <tt>w.x.y.z</tt> is the
-source IP address which is attempting to deliver mail to your server. For
-example, <a href="http://www.spamcop.net">SpamCop</a> would use the query
-<tt>2.0.0.127.bl.spamcop.net</tt> to determine whether the host at
-<tt>127.0.0.2</tt> is a known spammer or open relay. In this case, you

+</p>
+<p>The other tool is an <a href="http://www.faqs.org/rfcs/rfc2033.html">RFC2033</a>
+compliant LMTP service running on a local socket. If you're
+running a mailer that speaks LMTP (such as <a
+ href="http://www.postfix.org/">Postfix</a>), you can simply point your
+mailer at the socket called <span style="font-family: monospace;">citadel.socket</span>
+in your Citadel directory. For example, in Postfix you might put
+the following line into <span style="font-family: monospace;">main.cf</span>
+in order to tell it to use Citadel to deliver mail to local recipients:<br>
+</p>
+<pre>local_transport = lmtp:unix:/usr/local/citadel/lmtp.socket<br></pre>
+<p>Postfix also has something called a "fallback transport" which can
+be used to implement Citadel as a "secondary" mail system on your
+server, while keeping the existing Unix mailboxes intact.
+However, it is beyond the scope of this document to detail the finer
+points of the configuration of Postfix or any other mailer, so refer to
+the documentation to those programs and keep in mind that Citadel has
+LMTP support.<span style="font-family: monospace;"></span></p>
+<p>There are actually <i>two</i> LMTP sockets. One is called
+<tt>lmtp.socket</tt> and the other is called <tt>lmtp-unfiltered.socket</tt>
+(both are found in your Citadel directory). The difference should be
+obvious: messages submitted via <tt>lmtp.socket</tt> are subject to
+any
+spam filtering you may have configured (such as SpamAssassin), while
+messages
+submitted via <tt>lmtp-unfiltered.socket</tt> will bypass the filters.
+You
+would use the filtered socket when receiving mail from an external MTA
+such
+as Postfix, but you might want to use the unfiltered socket with
+utilities
+such as fetchmail.</p>

+<p>For outbound mail, you
+can either allow Citadel to perform
+deliveries directly
+(this won't affect your other mail system because outbound mail doesn't

<p>Citadel supports two modes of mailing list delivery: </p>
-

- <li>"List mode" -- each individual message is delivered as a single
-e-mail to each list mode recipient. The "From:" header will display
-the address of the message's original author.</li>
- <li>"Digest mode" -- groups of one or more messages are delivered to
-digest mode recipients. The number of messages in the group depends
-on how many new messages arrived since the last batch was delivered. The

- A room may have any combination of list mode and digest mode recipients.
-
-<p>As alluded to above, every room on your Citadel system has an Internet
- e-mail address of its own. Messages sent to that address will be posted
- in the room (and sent back out to mailing list recipients, as well as to
-any other Citadels you share the room with). The address format is
-<tt>room_</tt> plus the name of the room, with any spaces replaced by underscores,
-followed by <tt>@</tt> and your hostname. For example, if your system is
-known as <tt>phlargmalb.orc.org</tt> on the Internet, and you have a room
- called <tt>Bubblegum Collectors</tt>, you can post to that room from anywhere
-on the Internet simply by sending an e-mail to <tt>room_bubblegum_collectors@phlargmalb.orc.org</tt>.
- When the message arrives, it's automatically posted in that room.</p>

+<p>When you answer "Yes" to self-service list subscribe/unsubscribe,
+you are
+enabling that feature. Now, all you have to do is tell the world about
+the
+web page they need to visit. It looks like this:</p>

-<p>In this example, the server is called <tt>foobar.baz.org</tt> and WebCit

-<p>Citadel offers a subscribe/unsubscribe facility that is more intuitive
- than other listservs. With most systems, sending commands to the listserv
- requires that you e-mail it commands in a special format. It's easy to get
-it wrong. Citadel simply uses your web browser. You select the list you
-want to subscribe or unsubscribe (hint: it's the list of rooms you've enabled
-self-service for), select whether you want list mode or digest mode, and
-enter your e-mail address. For security purposes, a confirmation message
- is sent to the address you enter. But you don't have to reply to the message
- in a weird format, either: the confirmation contains another URL which you
- simply click on (or paste into your browser if you can't click on URL's

- There is no need to shut down Citadel during backups. The data store

+<span style="font-weight: bold;">Please read this section carefully.</span><br>
+<br>
+There are two backup strategies you can use, depending on your site's
+availability requirements and disk space availability.<br>
+<h5>Strategy #1: Standard backup</h5>
+The standard (or "offline") backup is used when your Citadel server is
+configured to automatically delete committed database logs. The
+backup procedure is as follows:<br>
+<ol>
+ <li>Shut down the Citadel server.</li>
+ <li>Back up all files (database files, log files, etc.) to tape or
+some other backup media.</li>
+ <li>Start the Citadel server.</li>
+</ol>
+<span style="font-style: italic;">Advantage:</span> very little disk
+space is consumed by the logs.<br>
+<span style="font-style: italic;">Disadvantage:</span> Citadel is not
+available during backups.<br>
+<br>
+<h5>Strategy #2: "Hot" backup</h5>
+The "hot backup" procedure is used when your Citadel server is
+configured <span style="font-weight: bold;">not</span> to
+automatically delete committed database logs. The backup
+procedure is as follows:<br>
+<ol>
+ <li>Back up all files. Make sure the database files (<span
+ style="font-family: monospace;">cdb.*</span>) are backed up <span
+ style="font-style: italic;">before</span> the log files (<span
+ style="font-family: monospace;">log.*</span>). This will usually
+be the case, because the database files tend to appear first in both
+alphabetical and on-disk ordering of the <span
+ style="font-family: monospace;">data/</span> directory.</li>
+ <li>After verifying that your backup completed successfully, delete
+the committed log files with a command like this:</li>
+</ol>
+<span style="font-family: monospace;">/usr/local/citadel/sendcommand
+"CULL"</span><br>
+<br>
+<span style="font-style: italic;">Advantage:</span> Citadel continues
+to run normally during backups.<span style="font-style: italic;"><br>
+Disadvantage:</span> Much disk space is consumed by the log files,
+particularly if the full text indexer is turned on.<br>
+<br>
+<br>
+It is up to you to decide which backup strategy to use. <span
+ style="font-weight: bold;">Warning: if you configure Citadel to
+automatically delete committed database logs, and do not shut the
+Citadel service down during backups, there is no guarantee that your
+backups will be usable!</span><br>

+<h2><a name="crypto"></a>Cryptography support (TLS/SSL)</h2>
+</center>
+<h3><a name="crypto_intro"></a>Overview</h3>
+<p>Citadel provides built-in support for encryption using Transport
+Layer Security (TLS) for ESMTP, IMAP, POP3, and the Citadel client
+protocol.
+A simple cryptographic configuration is installed automatically when
+you
+bring the system online. The remainder of this section describes how
+this
+configuration is built, and what you can do to make changes to it.</p>
+<p>Encryption files are kept in the <tt>keys/</tt> directory. The
+three
+files used by Citadel are:</p>
+<ul>
+ <li><tt>citadel.key</tt> - Contains your system's RSA private key.
+Citadel
+generates a new key automatically if one is not found. </li>
+ <li><tt>citadel.csr</tt> - Contains a Certificate Signing Request
+(CSR)
+for your system. Citadel generates a new CSR automatically, using your
+private key, if one is not found. </li>
+ <li><tt>citadel.cer</tt> - Contains the public certificate for your
+system. The public key in the certificate <b>must</b> correspond with
+the
+private key in <tt>citadel.key</tt>, otherwise encryption will not
+function properly. Citadel will generate a self-signed certificate,
+again
+using your private key, if a certificate is not found. </li>
+</ul>
+<h3><a name="real_cert"></a>Generating and installing a Trusted
+Certificate</h3>
+<p>If you wish to interact with 3rd party clients
+that have hard coded lists of acceptable Certificate Authorities, and
+you
+do not want annoying dialog boxes popping up for the user on the first
+(or
+all) connections, then you will have to have your key signed by a valid
+Certificate Authority.</p>
+<p>It is beyond the scope of this document to provide a complete
+tutorial
+on SSL certificates. Here are the general rules to follow:</p>
+<ul>
+ <li>Generally, the Certificate Signing Requeste which is
+automatically
+generated by Citadel will not contain enough information for any
+Certificate
+Authority to sign it. Generate a new CSR with the following commands:<br>
+ <br>
+ <tt>cd keys</tt><br>
+ <tt>openssl req -new -key citadel.key -out citadel.csr</tt><br>
+ <br>
+Answer all questions (your geographic location, organization name,
+etc.)
+and then send the new <tt>citadel.csr</tt> to your Certificate
+Authority
+when you order the certificate. </li>
+ <li>When the certificate is received, simply save it as <tt>citadel.cer</tt>
+and restart the Citadel server. </li>
+ <li>If your certificate authority delivers a 'chained' certificate
+(one
+with intermediate certificate authorities), simply append the
+intermediate
+certificate after your server's own certificate in the <tt>citadel.cer</tt>
+file.</li>

+<h2><a name="LDAP_Directory_Support"></a>LDAP (Directory) Support</h2>
+<div style="text-align: justify;">
+<h3><a name="Introduction_ldap"></a>Introduction</h3>
+LDAP (Lightweight Directory Access Protocol) has become the open
+standard protocol for directory access. There are many client
+programs which are capable of making use of an LDAP directory
+service. Therefore it may be beneficial for some sites to have a
+directory available which is populated with Citadel user information.<br>
+<br>
+Citadel does not contain its own LDAP service, because that would
+eliminate its ability to coexist with any existing directory you may
+already have in place at your organization. Instead, we provide
+the LDAP Connector for Citadel, which allows the Citadel service to
+populate an external LDAP directory. If you do not already have
+an LDAP directory in place, you can use the OpenLDAP server, which is
+probably already present in your operating system, or at least can be
+loaded from the installation CD's. The supplied configuration
+file <tt>citadel-slapd.conf</tt> can be used as a starting
+point to get your LDAP server running.<br>
+<br>
+<h3><a name="Preparing_your_LDAP_server_for_Citadel"></a>Preparing your
+LDAP server for Citadel connections</h3>
+It is difficult to find a commonly accepted LDAP scheme. It seems, most
+real life LDAP installations go for the domain oriented apporach
+and lay out the structure after an existing domain/subdomain structure.
+<p> The most widely accepted and standardized object for storing
+personal data clearly is "inetOrgPerson". Citadel therefore extends this
+standard schema with an object class called "citadelInetOrgPerson".</p>
+<p>If you are using OpenLDAP as your directory server, you should
+choose options similar to the following:</p>
+<pre>
+include /etc/openldap/schema/core.schema
+include /etc/openldap/schema/cosine.schema
+include /etc/openldap/schema/inetorgperson.schema
+include /etc/openldap/schema/rfc2739.schema
+include /etc/openldap/schema/citadel.schema
+

-<LI><b>whobbs</b> - Who is on the system

-</UL></p>
-
-<p>It is up to you to decide which utilities should be made accessible only
-to system administrators.
-It is important that you set the file permissions correctly. All
-utilities should have access to the Citadel data files. We will attempt to
-address each program individually.</p>
-
+<p>Notes on this configuration:
+<ul>
+ <li>Obviously, you can make your suffix and rootdn whatever you wish,
+but in most cases you'd simply follow a DC path that looks similar to
+your DNS domain.</li>
+ <li>In earlier versions of OpenLDAP, you could use the
+option <span style="font-family: monospace;">schemacheck off</span> to
+make life easier by relaxing the strict schema checking. This option
+has been removed from OpenLDAP, so now you <strong>must</strong> install
+the supplied schema extensions. <tt>rfc2739.schema</tt> and
+<tt>citadel.schema</tt> are included with the Citadel distribution.</li>
+ <li>Your <span style="font-family: monospace;">rootdn</span> and <span
+ style="font-family: monospace;">rootpw</span> can be whatever you
+want. Usually the rootdn is <span style="font-family: monospace;">cn=manager,</span>
+followed by your usual suffix. Please don't use <span
+ style="font-family: monospace;">secret</span> as your password, as in
+this example. Select a new password for your site.</li>
+</ul>
+<br>
+Your LDAP service <span style="font-weight: bold;">must</span> be up
+and running before you attempt to connect Citadel to it.<br>
+<br>
+<h3><a name="Configuring_the_LDAP_Connector_for"></a>Configuring the
+LDAP Connector for Citadel</h3>
+Once you've located or installed your LDAP server, connecting Citadel
+to it is easily completed with the <span style="font-weight: bold;"><span
+ style="font-family: monospace;">.A</span></span><span
+ style="font-family: monospace;">ide <span style="font-weight: bold;">S</span>ystem-configuration
+<span style="font-weight: bold;">G</span>eneral command:<br>
+</span>
+<pre>Lobby> . Aide System configuration General<br><br><span
+ style="font-style: italic;">(lots of other stuff omitted for brevity...)</span><br><br>Connect this Citadel to an LDAP directory [Yes]: <span
+ style="font-weight: bold;">Yes</span><br>Host name of LDAP server []: <span
+ style="font-weight: bold;">127.0.0.1</span><br>Port number of LDAP service [389]: <span
+ style="font-weight: bold;">389</span><br>Base DN []: <span
+ style="font-weight: bold;">dc=servername,dc=domain,dc=org</span><br>Bind DN []: <span
+ style="font-weight: bold;">cn=manager,dc=servername,dc=domain,dc=org</span><br>Password for bind DN []: <span
+ style="font-weight: bold;">secret</span><br style="font-weight: bold;"><br><span
+ style="font-style: italic;">(more questions omitted...)</span><br><br>Save this configuration? <span
+ style="font-weight: bold;">Yes</span><br></pre>
+Once you've done this, restart your Citadel service with the <span
+ style="font-weight: bold;"><span style="font-family: monospace;">.A</span></span><span
+ style="font-family: monospace;">ide <span style="font-weight: bold;">T</span>erminate-server
+<span style="font-weight: bold;">N</span>ow</span> command. When
+Citadel restarts, it will connect to your LDAP directory. Note
+that we gave Citadel the same Base DN, Bind DN, and password that was
+in our LDAP server configuration example. Obviously, everything
+needs to be identical on both sides or the connection will be
+refused. 127.0.0.1 is the loopback address, and 389 is the
+standard port number for LDAP, so this would be the proper host and
+port combination for an LDAP service running on your local
+server. It could just as easily be on another server, for example
+an organization-wide directory server.<br>
+<br>
+You can also configure the LDAP Connector for Citadel from a WebCit
+session. Log on as an Aide and click on Advanced Options -->
+Edit Site-Wide Configuration --> Directory, and you will be
+presented with the same set of questions.<br>
+<br>
+So, what kind of information will be entered into LDAP? As a
+rule, anything that gets saved to your Global Address Book room will
+also be saved to LDAP. Citadel will set up OU's (Organizational
+Units) for each node on your Citadel network, so if you are running
+multiple Citadel servers in an organization, you will automatically
+have a hierarchial view built for you. Below the OU's will be an
+entry for each user who has a vCard registered on the system.
+Citadel automatically translates vCard information to LDAP.<br>
+<br>
+If you already have a Global Address Book full of existing information,
+you can execute an <span style="font-family: monospace;">IGAB</span>
+(Initialize Global Address Book) server command to rebuild it. In
+addition to performing its usual function of rebuilding the internal
+Internet e-mail address mapping table, Citadel will also repopulate
+LDAP with all existing vCards. You should be aware, however, that
+existing LDAP entries will not be cleared from your directory
+server. If your directory contains only Citadel data, you can
+safely delete your database and start over, because it will be
+repopulated. Otherwise, Citadel will merely update any existing
+records with fresh information.<br>
+<br>
+The LDAP Connector for Citadel is a recent development, so expect more
+functionality in this space in the near future.<br>

-of connects, number of logins, number of logouts, number of disconnects,
-bad password attempts, etc. All statistics are provided in three figures:
-times per call, times per day, and total times.</p>
-
-<p>After this screen appears, you may press return for the next screen. This
-is a graphic representation of system usage, broken down into 20 minute
-segments of the day. This will show you when your peak usage is.</p>
-
-<p>Press return again and the stats program will list your system's top
-20 callers.</p>
-
-<p>The final screen lists the twenty users with the highest post per call
