 SYNOPSIS
      #include <rle.h>

      char * rle_putcom( value, the_hdr )
      char * value;
      rle_hdr * the_hdr;

      char * rle_getcom( name, the_hdr )
      char * name;
      rle_hdr * the_hdr;

      char * rle_delcom( name, the_hdr )
      char * name;
      rle_hdr * the_hdr;

 DESCRIPTION
      Rle_putcom can be used to add a picture
      comment or change the value of a picture
      comment in a rle_hdr(3) structure.  The
      argument value is the string value of the
      comment, and is generally of the form
      name=value.  It may also be of the form name.
      If there is another comment with the same
      name, it will be replaced with the new value,
      and the previous comment will be returned as
      the value of rle_putcom.

      Rle_getcom returns a pointer to the data
      portion of a picture comment from an RLE
      file.  The comment is assumed to be in the
      form name=value; a pointer to value is
      returned.  If the comment is of the form
      name, a pointer to the null character at the
      end of the string is returned.  If there is
      no comment of the above forms, a NULL pointer
      is returned.  The the_hdr structure contains
      the picture comments in question.

      Rle_delcom is used to delete a picture
      comment from a rle_hdr(3) structure.  It is
      called with the name of the comment and the
      the_hdr structure to be modified.  The first
      comment in the rle_hdr structure of the form
      name=value or name will be deleted.  The
      deleted comment will be returned as the
      function value.
