- 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 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) 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 subroutines 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. 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
