The xstuff server is a mail-response program. That means that you mail
it a request, and it mails back the response.  Any of the four possible
commands must be the first word on a line.  The xstuff server reads your
entire message before it does anything, so you can have several different
commands in a single message (unless you ask for help).  The xstuff server
treats the "Subject:" header line just like any other line of the message.

	The archives are organized into a series of directories and
subdirectories.  Each directory has an index, and each subdirectory has an
index. The top-level index gives you an overview of what is in the
subdirectories, and the index for each subdirectory tells you what is in it.

	1) The command "help" or "send help" causes the server to send you a
more detailed version of this help file.
	2) if your message contains a line whose first word is "index", then
the server will send you the top-level index of the contents of the archive.
If there are other words on that line that match the name of subdirectories,
then the indexes for those subdirectories are sent instead of the top-level
index.  For example, you can say "send index fixes" (or "index fixes"). A
message that requests an index cannot request data.
	3) if your message contains a line whose first word is "send", then
	the xstuff server will send you the item(s) named on the rest of the
line. To name an item, you give its directory and its name. For example
		send fixes 1 4 8a 8b 9 
You may issue multiple send requests.
	The xstuff server contains many safeguards to ensure that it is not
monopolized by people asking for large amounts of data. The mailer is set up
so that it will send no more than a fixed amount of data each day. If the work
queue contains more requests than the day's quota, then the unsent files will
not be processed until the next day.  Whenever the mailer is run to send its
day's quota, it sends the requests out shortest-first.
	4) Some mailers produce mail headers that are unusable for extracting
return addresses.  If you use such a mailer, you won't get any response.  If
you happen to know an explicit path, you can include a line like
	path foo%bar.bitnet@mitvma.mit.edu or path bar!foo!frotz in the body
	of your message, and the daemon will use it.

	The xstuff server itself can be reached at xstuff@x.org.  If your
mailer deals in "!" notation, try sending to
{someplace}!mit-eddie!x.org!xstuff.
