HOW TO USE THE HIW DOCUMENT SERVER
----------------------------------

The HIW document server will mail back to you one or more of the
HIW documents.  Follow these simple steps to use this server:

Send an email message to

   hiw@sugs.tware.com

with one or more document names, or, one or more server commands,
in the message body.  Place one document name or server command
per line in the message body.  The subject line of the message is
ignored.

The server will process each line of the message body until one
of the following happens:

   a) A line with the word END is found.

   b) A line with data other than alphnumeric characters is found.

You will receive one or more email messages from the server for
each document requested.  The server will respond to document
requests approximately once every 24 hours.

Additional rules and notes:

   a) Document names and server commands can be in upper or lower
      case.

   b) Additional data to the right of a document name or server
      command is ignored.

   c) Blank lines are ignored.
