=head1 TITLE
Perl6's License Should Be a Minor Bugfix of Perl5's License
=head1 VERSION
Maintainer: Bradley M. Kuhn E<lt>[EMAIL PROTECTED]<gt>
Date: 13 Sep 2000
Mailing List: [EMAIL PROTECTED]
Number: 219
Version: 1
Status: Developing
Requires: RFC 211: The Artistic License Must Be Changed
=head1 ABSTRACT
This is a minimalist approach to the licensing for perl6. The only change
from perl5 is some minor changes to the Artistic License. The Artistic
license is changed to clarify it better legally, yielding "The Clarified
Artistic License" (referred to "AL-Clarified" for short). The overall
license of perl6 would remain a dual-license, the disjunction of the GPL and
AL-Clarified.
=head1 DESCRIPTION
This proposal takes a minimalist approach for the licensing of perl6.
The only change between the license proposed here and the license of perl5
is some minor changes to the Artistic License. These changes fix only a few
minor problems in the Artistic License to clarify some points, and ensure
that it is a free software license. (See L<RFC211> for reasons why the
Artistic License should be changed.)
Thus, this RFC proposes two measures:
=over 8
=item
The Artistic License is updated I<as little as possible> to make it more
legally sound and to ensure it is definitely a free software license without
question nor reservation. This yields a variant of the Artistic License
which has been dubbed "The Clarified Artistic License".
=item
The license of perl6 itself will be a dual-license, the disjunction of the
GNU General Public License and The Clarified Artistic License.

=head1 IMPLEMENTATION
=head2 The Clarified Artistic License
The Clarified Artistic License is provided in two forms here. First, it is
provided as a patch against the current Artistic License. Second, the
entire text of the Clarified Artistic License is included.
=head3 Patch to Change the Artistic License into the Clarified Artistic License
# Change the Artistic License into the Clarified Artistic License
#
# To apply this patch:
# STEP 1: Chdir to the source directory.
# STEP 2: Run the 'applypatch' program with this patch file as input.
#
# If you do not have 'applypatch', it is part of the 'makepatch' package
# that you can fetch from the Comprehensive Perl Archive Network:
# http://www.perl.com/CPAN/authors/Johan_Vromans/makepatch-x.y.tar.gz
# In the above URL, 'x' should be 2 or higher.
#
# To apply this patch without the use of 'applypatch':
# STEP 1: Chdir to the source directory.
# STEP 2: Run the 'patch' program with this file as input.

=head3 The Full Text of the Clarified Artistic License
The Clarified 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.
"Distribution fee" is a fee you charge for providing a copy
of this Package to another party.
"Freely Available" means that no fee is charged for the right to
use the item, 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 network
archive site allowing unrestricted access to them, 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 distribution fee for any distribution of this Package.
If you offer support for this Package, you may charge any fee you choose
for that support. You may not charge a license fee for the right to use
this Package itself. You may distribute this Package in aggregate with
other (possibly commercial and possibly nonfree) programs as part of a
larger (possibly commercial and possibly nonfree) software distribution,
and charge license fees for other parts of that 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.
