                     The "Artistic License" for Tree

                                Preamble

The intent of this document is to state the conditions under which the Tree
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 the CHANGES file stating what
   changes were made and to what, 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 name of the Copyright Holder may not be used to endorse or promote
   products derived from this software without specific prior written
   permission.

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