The output of vers_string has the following format: PROGRAM:prog PROJECT:proj&vers DEVELOPER:bob BUILT:Thu Dec 31 ... prog is the command 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
