3 * anno.c -- annotate messages
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.
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.
15 * The -draft option causes anno to operate on the current draft file
16 * instead of on a message sequence.
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.
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.
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.
