MM     

mm is a powerful electronic mail system which allows you to send, read, edit
  and manage messages quickly and easily.  

mm features the CCMD package developed at Columbia.  It has extensive internal
  help, recognition of abbreviated commands, completion of partly typed 
  commands by use of the TAB key, and help on partly typed commands by use 
  of the question-mark key.  (Type "help ccmd" for more detail.)

mm can read several mail-file formats.  Its default is mbox, the same 
   format used by ucb "mail".  It also can read babyl, used by emacs, and 
   mtxt, and it can copy messages from one file type to another.

You are now at the TOP-LEVEL, indicated by the prompt "MM>".  There are
two other specialized "modes" in MM:

   READ MODE	prompt Read> or R>	handles a message you are reading.
   SEND MODE    prompt Send> or S>      handles a message you are sending.
  
The most commonly used commands at TOP-LEVEL are:
 SEND		to write and send mail-- takes you to SEND MODE
 READ		to read incoming mail-- takes you to READ MODE
 HEADERS	to see an index of mail you have saved
 HELP and ?	to get online help-- see the next paragraph  
 EXIT or QUIT   to leave MM

The HELP command shows help screens about MM commands, topics, and variables.
  Type "help help" for information about the HELP command.  Type "help ?"
  ("help", space, question-mark) for a list of all commands and topics for 
  which help is available.
