Modified Clarified Artistic License

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.

To make the interpretation clear, see also the Questions and Answers
section at http://code.google.com/p/evennia/wiki/Licensing .

   modified, or has been modified in accordance with the wishes of the
   Copyright Holder as specified below.

Licence Regulations
-------------------

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 those made Freely Available, 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:
   1. 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 network archive site allowing unrestricted access to
      them, or by allowing the Copyright Holder to include your
      modifications in the Standard Version of the Package.
   2. 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:
   1. 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.
   2. accompany the distribution with the machine-readable source of
      the Package with your modifications.
   3. 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.
   4. make other distribution arrangements with the Copyright Holder.
   5. offer the machine-readable source of the Package, with your
      modifications, by mail order.

5. You may charge a distribution fee for any distribution of this
   Package. If you offer support for this Package, you may charge any
   fee you choose for that support. You may not charge a license fee
   for the right to use this Package itself. You may distribute this
   Package in aggregate with other (possibly commercial and possibly
   nonfree) programs as part of a larger (possibly commercial and
   possibly nonfree) software distribution, and charge license fees
   for other parts of that software distribution, provided that you do
   not advertise this Package as a product of your own. If the Package
   includes an interpreter, 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 (especially the custom-created files
   created for making use of the Package) 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 whoever 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 the Standard Version of the 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. Credits and attributions in the headers of all source and
    documentation files must be left intact.

11. 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.
