			       PROM LICENCE
			   (as of 22 April 1992)


Copyright (c) 1991, 1992  by  Thilo Kielmann,  Technical  University  of
Darmstadt.  Everyone is permitted to copy and distribute verbatim copies
of  this  licence,  but changing  it  is not allowed.  You can also  use
this wording to make the terms for other programs. This licence is based
on (but not equal to)  the General Public Licence  of the  Free Software
Foundation.

This licence agreement is intended to give anyone  the  right  to  share
PROM for  non-commercial  use.   To make  sure that  you get  the rights
we  want you to have, we need to make restrictions that forbid anyone to
deny you these rights or to ask you to surrender the rights.  Hence this
licence agreement.

Specifically, we want to make sure that you have the right to give  away
copies  of  PROM,  that you  receive  source code  or else can get it if
you  want  it, that  you  can  change  PROM  or use  pieces of it in new
free programs, and that you know you can do these things.

To make sure that everyone has such rights, we have  to  forbid  you  to
deprive  anyone  else  of  these rights.  For example, if you distribute
copies of  PROM,  you must  give  the  recipients  all the  rights  that
you  have.   You  must  make sure that they, too, receive or can get the
source code.  And you must give them a verbatim copy of this licence  to
tell them their rights.

Also, for our own protection, we must make certain that  everyone  finds
out that  there is  no warranty  for    PROM.  If   PROM   is   modified
by  someone else and passed on, we want its recipients to know that what
they have is not what we distributed, so that any problems introduced by
others will not reflect on our reputation.

Therefore we (Thilo Kielmann and the  Institute of  Theoretical Computer
Science of the Technical University Darmstadt) make the following  terms
which say what you must do to be allowed to distribute  or  change PROM.



			  COPYING POLICIES

  1.  You  may  copy  and  distribute  verbatim  copies  of  the    PROM   
source code  as  you receive  it, on any   medium,   provided that   you
conspicuously  and appropriately publish on each  copy a valid copyright
notice  "(c) 1991, 1992  by  T.Kielmann and  TH Darmstadt/ITI"  and  the
author's  address; keep  intact the  notices  on  all files  that  refer
to this Licence Agreement  and  to  the  absence  of  any warranty;  and
give any other recipients  of the PROM program a  copy of  this  Licence
Agreement along with the program. You may charge a  distribution fee for
the physical act of transferring a copy.

  2.  You may modify your copy or copies of    PROM     source  code  or
any  portion of it, and copy and distribute such modifications under the
terms of Paragraph 1 above, provided that you also do the following:

    a) cause the modified files to carry prominent notices stating  that
    you changed the files and the date of any change; and

    b) cause the whole of any work that you distribute or publish,  that
    in whole or in part contains or is a derivative of    PROM    or any
    part  thereof,  to  be licensed at no charge to all third parties on
    terms identical to those contained in this Licence Agreement (except
    that you may choose to grant more extensive warranty  protection  to
    some or all third parties, at your option).

    c) you may charge  a  distribution  fee  for  the  physical  act  of
    transferring  a  copy,  and  you  may  at your option offer warranty
    protection in exchange for a fee.

Mere aggregation of another unrelated program with this program (or  its
derivative)  on  a  volume  of a storage or distribution medium does not
bring the other program under the scope of these terms.

  3.  You may copy and distribute    PROM    (or a portion or derivative
of it, under Paragraph 2) in object code or executable  form  under  the
terms  of  Paragraphs 1 and 2 above provided that you also do one of the
following:

    a) accompany it with  the  complete  corresponding  machine-readable
    source code, which must be distributed under the terms of Paragraphs
    1 and 2 above; or,

    b) accompany it with a written  offer,  valid  for  at  least  three
    years,  to  give any third party free (except for a nominal shipping
    charge) a complete machine-readable copy of the corresponding source
    code, to be distributed under the terms of Paragraphs 1 and 2 above;
    or,

    c) accompany it with the information you received as  to  where  the
    corresponding  source  code  may  be obtained.  (This alternative is
    allowed only for noncommercial distribution and only if you received
    the program in object code or executable form alone.)

For an executable file, complete source code means all the  source  code
for  all  modules  it contains; but, as a special exception, it need not
include source code  for  modules  which  are  standard  libraries  that
accompany the operating system on which the executable file runs.

  4.  You  may  not  copy,  sublicense,  distribute  or  transfer   PROM   
except  as expressly provided under this Licence Agreement.  Any attempt
otherwise to copy, sublicense, distribute or transfer    PROM    is void
and your rights to use    PROM    under this Licence Agreement shall  be
automatically  terminated.   However, parties who have received computer
software programs from you with this Licence  Agreement  will  not  have
their  licences  terminated  so  long  as  such  parties  remain in full
compliance.

  5.  If you wish to incorporate parts of PROM into other programs whose
distribution conditions are different, contact the author.

  6.  If you base research on PROM  and publish  on this  research,  you
must include appropriate acknowledgements and references to PROM in your
publication.



			   NO WARRANTY

  BECAUSE PROM  IS LICENSED  FREE OF  CHARGE, WE  PROVIDE  ABSOLUTELY NO
WARRANTY,  TO  THE  EXTENT  PERMITTED  BY  APPLICABLE  LAW.  EXCEPT WHEN
OTHERWISE  STATED  IN  WRITING, THE  TECHNICAL  UNIVERSITY  OF DARMSTADT,
THILO  KIELMANN  AND/OR  OTHER  PARTIES  PROVIDE  PROM  "AS IS"  WITHOUT
WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,  INCLUDING,  BUT  NOT
LIMITED TO, THE IMPLIED WARRANTIES OF  MERCHANTABILITY  AND  FITNESS FOR
A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND  PERFORMANCE
OF THE PROGRAM IS WITH YOU. SHOULD THE PROM PROGRAM PROVE DEFECTIVE, YOU
ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

 IN NO  EVENT UNLESS  REQUIRED BY  APPLICABLE  LAW  WILL  THE  TECHNICAL
UNIVERSITY OF DARMSTADT, THILO KIELMANN, AND/OR  ANY OTHER PARTY WHO MAY
MODIFY AND REDISTRIBUTE PROM AS PERMITTED ABOVE, BE LIABLE  TO  YOU  FOR
DAMAGES,  INCLUDING  ANY  LOST  PROFITS,  LOST MONIES, OR OTHER SPECIAL,
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR  INABILITY
TO USE (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
INACCURATE  OR  LOSSES  SUSTAINED  BY  THIRD PARTIES OR A FAILURE OF THE
PROGRAM  TO  OPERATE  WITH  PROGRAMS  NOT  DISTRIBUTED  BY THE TECHNICAL
UNIVERSITY OF DARMSTADT) THE PROGRAM,  EVEN IF YOU HAVE  BEEN ADVISED OF
THE POSSIBILITY OF SUCH DAMAGES, OR FOR ANY CLAIM BY ANY OTHER PARTY.
