ETC Element v2.1.0 - Manual (Page 311)

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.
