Preamble

  The intent of this document is to state the conditions under which a
  Package may be copied, such that the Copyright Holder maintains some
  semblance of artistic control over the development of the package,
  while giving the users of the package the right to use and distribute
  the Package in a more-or-less customary fashion, plus the right to
  make reasonable modifications.

Definitions

  "Package" refers to the collection of files distributed by the Copyright
  Holder, and derivatives of that collection of files created through
  textual modification.

  "Standard Version" refers to such a Package if it has not been modified,
  or has been modified in accordance with the wishes of the Copyright
  Holder as specified below.

  "Copyright Holder" is whoever is named in the copyright or copyrights
  for the package.

  "You" is you, if you're thinking about copying or distributing this
  Package.

  "Reasonable copying fee" is whatever you can justify on the basis
  of media cost, duplication charges, time of people involved, and so
  on. (You will not be required to justify it to the Copyright Holder,
  but only to the computing community at large as a market that must
  bear the fee.)

  "Freely Available" means that no fee is charged for the item itself,
  though there may be fees involved in handling the item. It also
  means that recipients of the item may redistribute it under the same
  conditions they received it.

1. You may make and give away verbatim copies of the source form of the
   Standard Version of this Package without restriction, provided that
   you duplicate all of the original copyright notices and associated
   disclaimers.

2. You may apply bug fixes, portability fixes and other modifications
   derived from the Public Domain or from the Copyright Holder. A Package
   modified in such a way shall still be considered the Standard Version.

3. You may otherwise modify your copy of this Package in any way,
   provided that you insert a prominent notice in each changed file
   stating how and when you changed that file, and provided that you do
   at least ONE of the following:

      a. place your modifications in the Public Domain or otherwise
         make them Freely Available, such as by posting said modifications
         to Usenet or an equivalent medium, or placing the modifications
         on a major archive site such as uunet.uu.net, or by allowing the
         Copyright Holder to include your modifications in the Standard
         Version of the Package.

      b. use the modified Package only within your corporation or
         organization.

      c. rename any non-standard executables so the names do not
         conflict with standard executables, which must also be provided,
         and provide a separate manual page for each non-standard
         executable that clearly documents how it differs from the
         Standard Version.

      d. make other distribution arrangements with the Copyright
         Holder.

4. You may distribute the programs of this Package in object code or
   executable form, provided that you do at least ONE of the following:

      a. distribute a Standard Version of the executables and library
         files, together with instructions (in the manual page or
         equivalent) on where to get the Standard Version.

      b. accompany the distribution with the machine-readable source of
         the Package with your modifications.

      c. give non-standard executables non-standard names, and clearly
         document the differences in manual pages (or equivalent),
         together with instructions on where to get the Standard Version.

      d. make other distribution arrangements with the Copyright Holder.

5. You may charge a reasonable copying fee for any distribution of
   this Package. You may charge any fee you choose for support of this
   Package. You may not charge a fee for this Package itself. However,
   you may distribute this Package in aggregate with other (possibly
   commercial) programs as part of a larger (possibly commercial)
   software distribution provided that you do not advertise this Package
   as a product of your own. You may embed this Package's interpreter
   within an executable of yours (by linking); this shall be construed
   as a mere form of aggregation, provided that the complete Standard
   Version of the interpreter is so embedded.

6. The scripts and library files supplied as input to or produced as
   output from the programs of this Package do not automatically fall
   under the copyright of this Package, but belong to whomever generated
   them, and may be sold commercially, and may be aggregated with this
   Package. If such scripts or library files are aggregated with this
   Package via the so-called "undump" or "unexec" methods of producing
   a binary executable image, then distribution of such an image shall
   neither be construed as a distribution of this Package nor shall it
   fall under the restrictions of Paragraphs 3 and 4, provided that you
   do not represent such an executable image as a Standard Version of
   this Package.

7. C subroutines (or comparably compiled subroutines in other
   languages) supplied by you and linked into this Package in order to
   emulate subroutines and variables of the language defined by this
   Package shall not be considered part of this Package, but are the
   equivalent of input as in Paragraph 6, provided these subroutines do
   not change the language in any way that would cause it to fail the
   regression tests for the language.

8. Aggregation of this Package with a commercial distribution is always
   permitted provided that the use of this Package is embedded; that
   is, when no overt attempt is made to make this Package's interfaces
   visible to the end user of the commercial distribution. Such use
   shall not be construed as a distribution of this Package.

9. The name of the Copyright Holder may not be used to endorse or
   promote products derived from this software without specific prior
   written permission.

10. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR IMPLIED
  WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF
  MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

The End
