/* Citadel/UX rcit $Id$
- * version 2.9
*
- * This program functions the same as the standard rnews program for
- * UseNet. It accepts standard input, and looks for rooms to post messages
- * (translated from UseNet format to the Citadel/UX binary message format)
- * in that match the names of the newsgroups. network/rnews.xref is checked
- * in case the sysop wants to cross-reference room names to newsgroup names.
- * If standard input is already in binary, the -c flag should be used.
- * The netproc program is then called to do the processing.
+ * This program simply feeds its standard input to the networker. It is
+ * used primarily to hook up to UUCP feeds of Citadel data.
*
- * If you have a separate newsreader and don't want to use Citadel for news,
- * just call this program something else (rcit, for example) -- but make sure
- * to tell your Citadel network neighbors the new name of the program to call.
*
* usage:
- * rnews [-c] [-z] [-s]
+ * rcit [-z] [-s]
* flags:
- * -c Input is already in Citadel binary format
- * (default is UseNet news format)
* -z Input is compressed, run uncompress on it before processing
* -s Don't run netproc now, just accept the input into spoolin
