   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.
