NAME
     errhdr - produce a C header file from a set of messages

SYNOPSIS
     errhdr [-2] [-s] msgfile [hdrfile]

DESCRIPTION
     errhdr  reads  a file describing error codes and corresponding messages and
     produces a C header file, either on standard output or in hdrfile.

     The input file has a simple text-based format; one  file  (errmsg/valid.msg
     in the source tree) starts

     MODULE valid
     $$ SEQ_INST, 1
     $^   ExtNotAllowed, 1
     # This is a comment
     A Bioseq "extension" is used for special classes of Bioseq. This class of
     Bioseq should not have one but it does. This is probably a software error.

     $^   ExtBadOrMissing, 2
     This class of Bioseq requires an "extension" but it is missing or of the
     wrong type. This is probably a software error.

     (Detailed	descriptions  are  optional,  and no "end" lines of any sort are
     necessary.)

OPTIONS
     A summary of options is included below.

     -2     Code, subcode tuples
