   3  * anno.c -- annotate messages
   4  *
   5  * This code is Copyright (c) 2002, by the authors of nmh.  See the
   6  * COPYRIGHT file in the root directory of the nmh distribution for
   7  * complete copyright information.
   8  *
   9  *      Four new options have been added: delete, list, number, and draft.
  10  *      Message header fields are used by the new MIME attachment code in
  11  *      the send command.  Adding features to generalize the anno command
  12  *      seemed to be a better approach than the creation of a new command
  13  *      whose features would overlap with those of the anno command.
  14  *
  15  *      The -draft option causes anno to operate on the current draft file
  16  *      instead of on a message sequence.
  17  *
  18  *      The -delete option deletes header elements that match the -component
  19  *      field name.  If -delete is used without the -text option, the first
  20  *      header field whose field name matches the component name is deleted.
  21  *      If the -delete is used with the -text option, and the -text argument
  22  *      begins with a /, the first header field whose field name matches the
  23  *      component name and whose field body matches the text is deleted.  If
  24  *      the -text argument does not begin with a /, then the text is assumed
  25  *      to be the last component of a path name, and the first header field
  26  *      whose field name matches the component name and a field body whose
  27  *      last path name component matches the text is deleted.  If the -delete
  28  *      option is used with the new -number option described below, the nth
  29  *      header field whose field name matches the component name is deleted.
  30  *      No header fields are deleted if none of the above conditions are met.
  31  *
  32  *      The -list option outputs the field bodies from each header field whose
  33  *      field name matches the component name, one per line.  If no -text
  34  *      option is specified, only the last path name component of each field
  35  *      body is output.  The entire field body is output if the -text option
  36  *      is used; the contents of the -text argument are ignored.  If the -list
  37  *      option is used in conjuction with the new -number option described
  38  *      below, each line is numbered starting with 1.  A tab separates the
  39  *      number from the field body.
  40  *
  41  *      The -number option works with both the -delete and -list options as
  42  *      described above.  The -number option takes an optional argument.  A
  43  *      value of 1 is assumed if this argument is absent.
