			 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 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 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 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.
