Formatted Messages
==================

   On systems which are based on System V messages of programs
(especially the system tools) are printed in a strict form using the
`fmtmsg' function.  The uniformity sometimes helps the user to
interpret messages and the strictness tests of the `fmtmsg' function
ensure that the programmer follows some minimal requirements.
