+** anno.c -- annotate messages
+**
+** This code is Copyright (c) 2002, by the authors of nmh. See the
+** COPYRIGHT file in the root directory of the nmh distribution for
+** complete copyright information.
+**
+** Three new options have been added: delete, list, and number.
+** Message header fields are used by the new MIME attachment code in
+** the send command. Adding features to generalize the anno command
+** seemed to be a better approach than the creation of a new command
+** whose features would overlap with those of the anno command.
+**
+** The -delete option deletes header elements that match the -component
+** field name. If -delete is used without the -text option, the first
+** header field whose field name matches the component name is deleted.
+** If the -delete is used with the -text option, and the -text argument
+** begins with a /, the first header field whose field name matches the
+** component name and whose field body matches the text is deleted. If
+** the -text argument does not begin with a /, then the text is assumed
+** to be the last component of a path name, and the first header field
+** whose field name matches the component name and a field body whose
+** last path name component matches the text is deleted. If the -delete
+** option is used with the new -number option described below, the nth
+** header field whose field name matches the component name is deleted.
+** No header fields are deleted if none of the above conditions are met.
+**
+** The -list option outputs the field bodies from each header field whose
+** field name matches the component name, one per line. If no -text
+** option is specified, only the last path name component of each field
+** body is output. The entire field body is output if the -text option
+** is used; the contents of the -text argument are ignored. If the -list
+** option is used in conjuction with the new -number option described
+** below, each line is numbered starting with 1. A tab separates the
+** number from the field body.
+**
+** The -number option works with both the -delete and -list options as
+** described above. The -number option takes an optional argument. A
+** value of 1 is assumed if this argument is absent.
