NAME
      rle_addhist - add a history comment to an RLE
      file.


 SYNOPSIS
      #include <rle.h>

      void  rle_addhist( argv, in_hdr, out_hdr )
      char **argv;
      rle_hdr *in_hdr, *out_hdr;


 DESCRIPTION
      rle_addhist is used to add history comments
      to the RLE(5) file in the form:
           HISTORY=cmd arg1 arg2 on Tue Sep 13
      01:06:49 WST 1988
      where cmd, arg1, etc. are the command line
      arguments which have been used to generate or
      filter this RLE file. The HISTORY comment is
      always appended to so that an accumulated
      history is kept along with a timestamp.
      Programs which generate RLE files should call
      rle_addhist as follows:
           rle_addhist(argv,(rle_hdr *)0,&out_hdr);
      Programs which filter RLE files should call
      rle_addhist as:
           rle_addhist(argv,&in_hdr,&out_hdr);
