You can refer to this document in Pod via "L<perlartistic>"
Or you can see this document by entering "perldoc perlartistic"
This is "The Artistic License". It's here so that modules,
programs, etc., that want to declare this as their distribu-
tion license, can link to it.
It is also one of the two licenses Perl allows itself to be
redistributed and/or modified; for the other one, the GNU
General Public License, see the perlgpl.
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 rea-
sonable 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
perl v5.8.8 2006-06-30 1
PERLARTISTIC(1) Perl Programmers Reference Guide PERLARTISTIC(1)
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.
Conditions
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 ori-
ginal 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 fol-
lowing:
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 modif-
ications in the Standard Version of the Package.
b) use the modified Package only within your corpora-
tion 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 docu-
ments how it differs from the Standard Version.
d) make other distribution arrangements with the Copy-
right 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
perl v5.8.8 2006-06-30 2
PERLARTISTIC(1) Perl Programmers Reference Guide PERLARTISTIC(1)
manual page or equivalent) on where to get the Stan-
dard 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 Copy-
right Holder.
5. You may charge a reasonable copying fee for any distri-
bution 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 distri-
bute this Package in aggregate with other (possibly com-
mercial) programs as part of a larger (possibly commer-
cial) 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 execut-
able 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 Pack-
age, but belong to whoever generated them, and may be
sold commercially, and may be aggregated with this Pack-
age. 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 con-
sidered 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 distribu-
tion is always permitted provided that the use of this
perl v5.8.8 2006-06-30 3
PERLARTISTIC(1) Perl Programmers Reference Guide PERLARTISTIC(1)
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.
