It came to our attention during the retreat that a large number of
people were not aware of the Jaquith tertiary archiver.  This message
is intended to get you started on the basics of Jaquith and encourage
you all to take advantage of the resource.

I.   Why should I use Jaquith?  

     1) Jaquith provides access to massive storage from your own
	workstation.  You simply put and get unix files from a mythical
	place called Jaquith from your own machine without worrying about
	the details.

     2) Jaquith is extremely simple to use. You type "jput myfile" to
	archive a file, "jget myfile" to retrieve one, and "jls" to see
	what you have archived.  There are more sophicated options but
	those three simple commands will do most of the trick.

     3) Jaquith is robust.  It has been in use for one year and there have
	been three instances of data loss, all of which occurred earlier 
	on and were due to munged tapes.  We will provide you with means
	of preventing that from happening.

     4) Jaquith never deletes files.  You can get to an arbitrary
        version of a file you have archived.
 
     5) Jaquith implements protected access so files can be kept private.


II.  How do I sign up?

     Create an account for me on your machine (so I can install 
     Jaquith for you).  The passwd line is:

rywang:EXjyru0mKUZag:5527:16:Randolph Wang,608-4 Evans,28284,525-2215:/home2/rywang:/bin/csh

     Send mail to rywang@cs.berkeley.edu.  The message should contain:

     1) A list of people who will be using Jaquith,
     2) A list of machine addresses from which people will be initiating
	Jaquith requests,
     3) Whether you want your data to be replicated (unreplicated data
	works faster but there is a slim chance of losing it).


III. How do I use it?

     Jaquith is organized as a number of "archives", each of which is
     like a file system in the sense that it has its own "root".  Each
     archive has its own directory structure.  Users don't have to 
     create or change Jaquith directory by hand (hence the lack of
     "jcd" or "jmkdir").  Instead, Jaquith automatically mirrors the 
     unix directory from which Jaquith operations are performed.

     Suppose your current working directory is /home/me and you 
     typed the following sequence of commands:

	jput foo
	jget foo
	jls

     Upon seeing the jput command, Jaquith looks for Jaquith 
     directories /home and /home/me in the default archive.  If they
     are not found, they are created.  And finally Jaquith stores
     foo in the Jaqauith directory /home/me.  Upon seeing the jget
     command, Jaquith intelligently retrieves /home/me/foo from the
     default archive and puts a copy of foo in the user's current
     working directory.  Similarly, jls lists the contents of Jaquith
     directory /home/me.
