-If a `\-component\ field' is not specified when \fIanno\fR is invoked,
-\fIanno\fR will prompt the user for the name of field for the annotation.

-The field specified should be a valid 822-style message field name,
-which means that it should consist of alphanumerics (or dashes) only.
-The body specified is arbitrary text.

+The
+.B -list
+switch produces a listing of the field bodies for header fields with
+names matching the specified component, one per line.
+The listing is numbered, starting at 1, if the
+.B -number
+switch is also used.
+A tab character separates the number and the field body.
+The field body is treated as if it is a file name, and only the final
+path name component is listed.
+The complete field body is listed if the
+.B -text
+switch is used; the argument to the
+.B -text
+switch is required but ignored.
+.PP
+The
+.B -delete
+switch removes header fields from messages.
+The first header field whose name matches the component is deleted if
+no other options are specified.
+If the
+.B -text
+switch is used in conjunction with the
+.B -delete
+switch, the first header field whose name matches the component and
+whose body matches the text is deleted.
+The text is treated as if it was a file name; if it begins with a
+slash, the entire field body must match the text, otherwise just the
+last path name component of the field body must match.
+If the
+.B -number
+switch is used in conjunction with the
+.B -delete
+switch, header field
+.I num
+whose name matches the component is deleted.
+The number matches that which is produced by the
+.B -list
