+DESCRIPTION
+    Perl is free software; you can redistribute it and/or modify it under
+    the terms of either:
+
+            a) the GNU General Public License as published by the Free
+            Software Foundation; either version 1, or (at your option) any
+            later version, or
+
+            b) the "Artistic License" which comes with this Kit.
+
+    This is "The Artistic License". It's here so that modules, programs,
+    etc., that want to declare this as their distribution license can link
+    to it.
+
+    For the GNU General Public License, see 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
+    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.
+
+  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 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.
+
+    The End
