NAME
       vers_string - produce version identification string

SYNOPSIS
       vers_string [ -[c | f | l] ] PROGRAM

DESCRIPTION
       Vers_string  outputs  a	string	made  up  of  the  SGS	version  name, the current user's login identifier, and the current time and date.
       Vers_string may only be used within an SGS project.

       The output of vers_string has the following format: PROGRAM:prog  PROJECT:proj&vers  DEVELOPER:bob  BUILT:Thu Dec 31 ...  prog is the  com-
       mand line argument PROGRAM, proj&vers is the name of the SGS version root, and bob is the user who built this version.

       If  the	-c option is used, the output is formed as a C declaration for the global character array SGS_VERS.  If the -l option is used, the
       output is formed like the -c option, but "PROGRAM" is replaced with "LIBRARY" and the declaration is static.  If the -f option is used, the
       output is simply the program name and suffixed with the current version number of the SGS version root.

       Vers_string is typically used within makefiles with a rule like: vers.c: ${OBJS}      vers_string -c ${PROGRAM} >vers.c
