When file requesting from Internet Rex capable addresses, you can issue
the following commands in your message:

FREQ <a file or wildcard> !<password, if needed>
  This will request the file, or files matching the wildcard given.  If
  you gave a password, that will be used to try to pick up the file. 
  For example:
    FREQ ALLFILES
    FREQ BRE*.ZIP
    FREQ SECRET.ZIP !Somepassword
  By default, these files will be sent back to you, one per message,
  Base64 (MIME) encoded.

UUENCODE
  Once issued, any files requested after this command will be sent
  UUencoded instead of Base64 encoded.

XXENCODE
  As for UUENCODE, any files requested after this command is issued
  will be sent XXencoded.

MIME
  This will set the encoding back to Base64 (MIME) encoded files if it 
  was set otherwise.

SIZE <some number>
  This will set the number of lines used per message to encode your
  files.  For instance:
    SIZE 1000
  will make each message a maximum of 1000 lines long.  Any file which
  takes more than 1000 lines to encode will be broken up into multiple
  messages and sent that way.  (Broken up messages will be sent as
  multipart MIME messages.)

HELP
  Will send you this help file....

REPLY-TO
  Will change the destination email address of the files sent after
  the command is issued.  For instance,
    REPLY-TO bob@somewhere.com
  will send any further requested files to the address bob@somewhere.com
  instead of the normal destination email address.

QUIT
  Any further commands issued after this one will be ignored.
