\section{Useful Lockers}

\begin{sloppy}
The following is a partial list of useful lockers.  To access them, type
{\tt add {\em filesystem}}.  Many of them have a file named README in
their top-level directory, which will have more information about the
filesystem, its layout, and whom to contact for more information.

\begin{description}
\item{\em gnu}\/ contains software written and distributed by the Free
Software Foundation, such as gcc, a C/C++/Objective C compiler; gdb, a
source-level debugger; gnuchess, a chess program; bison, a replacement
for YACC; and gas, an assembler.  These programs are available in
varying degrees for various platforms.  Send any problems or questions
to {\em gnu@athena.mit.edu}.

\item{\em consult}\/ contains software written and/or maintained by
Athena's MIT-IS-CSS\footnote{That's Massachusetts Institute of
Technology Information Systems Computer Support Services.  Sigh.}
Consultants.  The {\em consult} locker contains programs for the vax,
rt, decmips, RS/6000, NeXT, and Sun4 machines.  Read {\em
/mit/consult/README} for instructions to use or learn about software
contained in {\em consult}. Send any problems or questions to {\em
consult@athena.mit.edu}.

\item{\em games}\/ is a random collection of games and puzzles.
Currently, the games locker supports games for vax, rt, decmips, and
RS/6000 to varying degrees, in addition to games to be run within Emacs.
The locker also contains source code for most of the games that are
installed.  Look at the {\em /mit/games/POLICY} file in the games locker
for rules about submissions.  Send any problems or questions to {\em
bug-games@athena.mit.edu}.


\item{\em info}\/ contains up-to-date information about the status of
Athena software and hardware, such as notices of impending or
emergency machine shutdowns.  Comments should be sent to {\em
bugs@athena.mit.edu}.

\item{\em net-directory}\/ contains the network directory produced at the
University of Texas, as well as other information about the Internet
network.  See the {\it README} file in {\it /mit/net-directory/README}
for more information.

\item{\em watchmaker}\/ is maintained by the so-called
``watchmakers,''\footnote{Read {\it The Mote in God's Eye} by Larry
Niven and Jerry Pournelle for an explanation of this term.} a group of
student systems programmers at Athena.  {\bf BEWARE!} Most of the
programs in the locker are esoteric and only useful to experienced
systems hackers, but some of the programs are of general interest.
Report any problems or bugs to {\it watchmakers@athena.mit.edu}.

\item{\em graphics} The graphics locker contains various
graphics-related programs useful for viewing and manipulating graphics.
See the {\bf Graphics} section of this guide for more information.

\item{\em postscript}\/  is a collection of interesting and
useful PostScript programs and utilities.  See the {\it discuss}\/
meeting on postscript\_hacks for information about what is currently
stored in the filesystem\footnote{Discuss is a conferencing system;
more details are in the {\bf Discuss} section or in the {\bf Using
Discuss} document, distributed by the SIPB}.  PostScript is a page
description language developed by Adobe Systems Inc.\ and is available
on all of Athena's printers.  It is a public locker, with world write
access turned on, so that anybody may place copies of useful
PostScript code into it for central storage.  Problems should be sent
to the discuss meeting above.

\item{\em perl}\/ Perl is an interpreted language that fills in the
area between shell programming and C programming.  The locker contains
both source and binaries, and various sample programs.  If you're
interested, you should also look in /afs/sipb.mit.edu/contrib/perl
\footnote{Look at either the {\bf AFS} section of this guide, or in
the SIPB document {\em Inessential AFS}.} a collection point for perl
contributions.

\item{\em rfc}\/ contains all the current Defense Advanced Research Projects
Agency (DARPA) Requests For Comment (RFC's).  These server are documents
on ``standards''.

\item{\em frame}\/ FrameMaker is an excellent but mostly untested
publishing tool, which handles word processing, books, page layout, and
graphics. You are encouraged to play around with it; it is a complicated
program, and very very new (as of August, 1993, anyway), but will be
supported by Athena. Documentation is being written even as you read
this, unless it's already done, in which case it will be available from
Graphic Arts. Look at the README file in {\em /mit/frame/README} for
more information.

\item{\em dotfiles}\/ The dotfiles locker contains a number of
extensively modified dotfiles. Many of these may be useful, and there
are a number of neat hacks that you can play with; but be {\em sure} you
know what you are doing before you hack your own dotfiles. Read the
README file in {\em /mit/dotfiles/README} for an explanation of how the
locker is set up.

\item Some other neat lockers are {\em shakespeare, bible} and {\em
weather}. They're just about exactly what you think they are. Look
around in them; ask your friends for their suggestions; see what you can
find on your own.
