				 Granted Rights

1. You are granted the non-exclusive rights set forth in this license
   provided you agree to and comply with any and all conditions in this
   license.  Whole or partial distribution of the Software, or software
   items that link with the Software, in any form signifies acceptance of
   this license.

   patches. The following restrictions apply to modifications:

     a. Modifications must not alter or remove any copyright notices in
        the Software.

     b. When modifications to the Software are released under this
        license, a non-exclusive royalty-free right is granted to the
        initial developer of the Software to distribute your modification
        in future versions of the Software provided such versions remain
        available under these terms in addition to any other license(s) of
        the initial developer.

4. You may distribute machine-executable forms of the Software or
   machine-executable forms of modified versions of the Software, provided
   that you meet these restrictions:

     a. You must include this license document in the distribution.

     b. You must ensure that all recipients of the machine-executable forms
        are also able to receive the complete machine-readable source code

        any charge beyond the costs of data transfer, and place prominent
        notices in the distribution explaining this.

     c. You must ensure that all modifications included in the
        machine-executable forms are available under the terms of this
        license.

   software items that link with the original or modified versions of the
   Software.  These items, when distributed, are subject to the following
   requirements:

        these items are also able to receive and use the complete
        machine-readable source code to the items without any charge
        beyond the costs of data transfer.

     b. You must explicitly license all recipients of your items to use
        and re-distribute original and modified versions of the items in
        both machine-executable and source code forms. The recipients must
        be able to do so without any charges whatsoever, and they must be
        able to re-distribute to anyone they choose.


     c. If the items are not available to the general public, and the
        initial developer of the Software requests a copy of the items,
        then you must supply one.

Artistic License

                               The "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.

        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.

           * "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
             ftp.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) accompany any non-standard executables with their
             corresponding Standard Version executables, giving the
             non-standard executables non-standard names, and clearly
             documenting 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.

        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.

        7. C or perl subroutines supplied by you and linked into this
        Package shall not be considered part of this Package.

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

        9. 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
