   organization contemplating export to obtain such a license
   before exporting.

WITHIN THAT CONSTRAINT, permission to use, copy, modify, and
distribute this software and its documentation for any purpose and
without fee is hereby granted, provided that the above copyright

This is the initial public distribution of the Kerberos Authentication
System.

A few notes:

IF YOU ARE OUTSIDE THE U.S. AND YOU WISH TO RETRIEVE THE CODE, you may
retrieve the file 'bones.tar.Z' (in the distribution directory mentioned
below), which is a version of the Kerberos source code WITH ALL
ENCRYPTION CODE REMOVED (and hence is exportable under general export
rules).  This code carries the same copyright and licensing terms as
found above, except that the paragraph about export licenses is not
applicable.  It will enable you to use the Kerberos protocols and
subroutines, but won't provide any network security.  You are free to
add your own encryption code (which will involve identifying places in
the code where an encryption routine should be called), but we cannot
help you, due to export regulations.  The 'bones' distribution is not at
the current patchlevel; after retrieving bones and unpacking it, examine
the file 'src/patchlevel.h' and get all patches with a number greater
than the number in that file (all the patches are available in the
directory in which you found this README file).

Export of the documentation is not restricted.

Read doc/installation.{mss,PS} first.  It explains how to set up
and compile Kerberos.

The current patchlevel is 9.

If you find bugs, please mail them to kerberos-bugs@ATHENA.MIT.EDU.

kerberos@ATHENA.MIT.EDU is a mailing list set up for discussing Kerberos
issues.  It is gatewayed to the Usenet newsgroup
'comp.protocols.kerberos'.  If you prefer to read it via mail, send a
request to kerberos-request@ATHENA.MIT.EDU to get added.

To retrieve the rest of the source code, change into the directory
'dist/900104'. 
[NOTE: you can't cd to this directory in steps, you must do it in one
command: cd dist/900104]
It contains several compressed & split tar files, plus a patch file.

To put them back together, concatenate all the files with similar names:
e.g. xxx.Z.aa and xxx.Z.ab get concatenated, save into xxx.Z, and
uncompress it, then apply patch file #9 (using the patch program, if
available).

NFS CHANGES:

Project Athena's changes to the Sun Network File System (NFS) are
available separately, via an automatic electronic-mail retrieval system.
Send mail with a subject of 'index krb-nfs' to
'archive-server@athena-dist.mit.edu' for more details.
