/*
* This file is derived from Bnews' fullname.c file.
* Bnews is Copyright (c) 1986 by Rick Adams.
*
* NOTICE: THIS CODE HAS BEEN MODIFIED TO FIT THE NN ENVIRONMENT:
*
* The full_name function has been rewritten entirely, although
* there are still some structural resemblence.
* Fullname checks $NAME before looking at /etc/passwd.
* The LOCALNAME alternative has been removed, because it would fit
* nn very poorly.
* The buildfname function is made static and moved before full_name.
*
* fullname.c - this file is made separate so that different local
* conventions can be applied. The stock version understands two
* conventions:
*
* (a) Berkeley finger: the gecos field in /etc/passwd begins with
* the full name, terminated with comma, semicolon, or end of
* field. & expands to the login name.
* (b) BTL RJE: the gecos field looks like
* : junk - full name ( junk :
* where the "junk -" is optional.
*
* If you have a different local convention, modify this file accordingly.
