 @section readmsg --- Extract messages from a folder.
 @pindex readmsg
 
-The program is currently in development
+The program, readmsg, extracts with the selection argument messages from
+a mailbox.  Selection can be specify by:
+
+@enumerate
+
+@item
+A lone ``*'' means select all messages in the mailbox.
+
+@item
+A list of message numbers may be specified.  Values
+of  ``0''  and ``$'' in the list both mean the last
+message in the mailbox.  For example:
+@example
+     readmsg 1 3 0
+@end example
+extracts  three messages from the folder:  the first, the third, and the last.
+
+@item
+Finally, the selection may be some text to match.  This  will  select  a  mail
+message which exactly matches the specified text.  For example,
+@example
+     readmsg staff meeting
+@end example
+extracts the message which contains the words ``staff meeting.''  Note that it
+will not match a message containing ``Staff Meeting'' - the matching  is  case
+sensitive.   Normally only the first message which matches the pattern will be
+printed.
+
+@end enumerate
+
+@subheading Command line options
+
+@table @samp
+
+@item -a
+@itemx --show-all
+If a pattern is use for selection show all messages that match pattern
+by default only the first one is presented.
+
+@item -d
+@itemx --debug
+Display mailbox debuging information.
+
+@item -f @var{MAILBOX}
+@itemx --folder=@var{MAILBOX}
+Specified the default mailbox.
+
+@item -h
+@itemx --header
+Show the entire header and ignore the weedlist.
+
+@item -n
+@itemx --no-header
+Do not print the message header.
+
+@item -p
+@itemx --form-feed
+Put form-feed (Control-L) between messages instead of newline.
+
+@item  -w @var{weedlist}
+@itemx --weedlist=@var{weedlist}
+A whitespace or coma separated list of header names to show per message.
+Default is --weedlist=''From Subject Date To CC Apparently-''
