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