The General Public License (GPL)

Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave,

Cambridge, MA 02139, USA. Everyone is permitted to copy and distribute

verbatim copies of this license document, but changing it is not allowed.

Preamble

The licenses for most software are designed to take away your freedom to share

and change it. By contrast, the GNU General Public License is intended to

guarantee your freedom to share and change free software--to make sure the

software is free for all its users. This General Public License applies to most of

the Free Software Foundation's software and to any other program whose

authors commit to using it. (Some other Free Software Foundation software is

covered by the GNU Library General Public License instead.) You can apply it to

your programs, too.

When we speak of free software, we are referring to freedom, not price. Our

General Public Licenses are designed to make sure that you have the freedom

to distribute copies of free software (and charge for this service if you wish), that

you receive source code or can get it if you want it, that you can change the

software or use pieces of it in new free programs; and that you know you can do

these things.

To protect your rights, we need to make restrictions that forbid anyone to deny

you these rights or to ask you to surrender the rights. These restrictions

translate to certain responsibilities for you if you distribute copies of the

software, or if you modify it.

For example, if you distribute copies of such a program, whether gratis or for a

fee, you must give the recipients all the rights that you have. You must make

sure that they, too, receive or can get the source code. And you must show

them these terms so they know their rights.

We protect your rights with two steps: (1) copyright the software, and (2) offer

you this license which gives you legal permission to copy, distribute and/or

modify the software.

Also, for each author's protection and ours, we want to make certain that

everyone understands that there is no warranty for this free software. If the

software is modified by someone else and passed on, we want its recipients to

know that what they have is not the original, so that any problems introduced by

others will not reflect on the original authors' reputations.

Finally, any free program is threatened constantly by software patents. We wish

to avoid the danger that redistributors of a free program will individually obtain

patent licenses, in effect making the program proprietary. To prevent this, we

have made it clear that any patent must be licensed for everyone's free use or

not licensed at all.

The precise terms and conditions for copying, distribution and modification

follow.

GNU GENERAL PUBLIC LICENSE

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND

MODIFICATION

0. This License applies to any program or other work which contains a notice

placed by the copyright holder saying it may be distributed under the terms of

this General Public License. The "Program", below, refers to any such program

or work, and a "work based on the Program" means either the Program or any

derivative work under copyright law: that is to say, a work containing the

Program or a portion of it, either verbatim or with modifications and/or translated

into another language. (Hereinafter, translation is included without limitation in

the term "modification".) Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not covered by

this License; they are outside its scope. The act of running the Program is not

restricted, and the output from the Program is covered only if its contents

constitute a work based on the Program (independent of having been made by

running the Program). Whether that is true depends on what the Program does.

1. You may copy and distribute verbatim copies of the Program's source code as

you receive it, in any medium, provided that you conspicuously and appropriately

publish on each copy an appropriate copyright notice and disclaimer of warranty;

keep intact all the notices that refer to this License and to the absence of any

warranty; and give any other recipients of the Program a copy of this License

along with the Program.

You may charge a fee for the physical act of transferring a copy, and you may at

your option offer warranty protection in exchange for a fee.

2. You may modify your copy or copies of the Program or any portion of it, thus

forming a work based on the Program, and copy and distribute such

modifications or work under the terms of Section 1 above, provided that you also

meet all of these conditions:

a) You must cause the modified files to carry prominent notices stating that you

changed the files and the date of any change.

b) You must cause any work that you distribute or publish, that in whole or in

part contains or is derived from the Program or any part thereof, to be licensed

as a whole at no charge to all third parties under the terms of this License.

c) If the modified program normally reads commands interactively when run, you

must cause it, when started running for such interactive use in the most ordinary

way, to print or display an announcement including an appropriate copyright

notice and a notice that there is no warranty (or else, saying that you provide a

warranty) and that users may redistribute the program under these conditions,

and telling the user how to view a copy of this License. (Exception: if the

Program itself is interactive but does not normally print such an announcement,

your work based on the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole. If identifiable

sections of that work are not derived from the Program, and can be reasonably

considered independent and separate works in themselves, then this License,

and its terms, do not apply to those sections when you distribute them as

separate works. But when you distribute the same sections as part of a whole

which is a work based on the Program, the distribution of the whole must be on

the terms of this License, whose permissions for other licensees extend to the

entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest your rights to

work written entirely by you; rather, the intent is to exercise the right to control

the distribution of derivative or collective works based on the Program.

In addition, mere aggregation of another work not based on the Program with the

Program (or with a work based on the Program) on a volume of a storage or

distribution medium does not bring the other work under the scope of this

License.

3. You may copy and distribute the Program (or a work based on it, under

Section 2) in object code or executable form under the terms of Sections 1 and 2

above provided that you also do one of the following:

a) Accompany it with the complete corresponding machine-readable source

code, which must be distributed under the terms of Sections 1 and 2 above on a

medium customarily used for software interchange; or,

b) Accompany it with a written offer, valid for at least three years, to give any

third party, for a charge no more than your cost of physically performing source

distribution, a complete machine-readable copy of the corresponding source

code, to be distributed under the terms of Sections 1 and 2 above on a medium

customarily used for software interchange; or,

c) Accompany it with the information you received as to the offer to distribute

corresponding source code. (This alternative is allowed only for noncommercial

distribution and only if you received the program in object code or executable

form with such an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for making

modifications to it. For an executable work, complete source code means all the

source code for all modules it contains, plus any associated interface definition

files, plus the scripts used to control compilation and installation of the

executable. However, as a special exception, the source code distributed need

not include anything that is normally distributed (in either source or binary form)

with the major components (compiler, kernel, and so on) of the operating system

on which the executable runs, unless that component itself accompanies the

executable.

If distribution of executable or object code is made by offering access to copy

from a designated place, then offering equivalent access to copy the source

code from the same place counts as distribution of the source code, even though

third parties are not compelled to copy the source along with the object code.

4. You may not copy, modify, sublicense, or distribute the Program except as

expressly provided under this License. Any attempt otherwise to copy, modify,

sublicense or distribute the Program is void, and will automatically terminate

your rights under this License. However, parties who have received copies, or

rights, from you under this License will not have their licenses terminated so long

as such parties remain in full compliance.

5. You are not required to accept this License, since you have not signed it.

However, nothing else grants you permission to modify or distribute the Program

or its derivative works. These actions are prohibited by law if you do not accept

this License. Therefore, by modifying or distributing the Program (or any work

based on the Program), you indicate your acceptance of this License to do so,

and all its terms and conditions for copying, distributing or modifying the

Program or works based on it.

6. Each time you redistribute the Program (or any work based on the Program),

the recipient automatically receives a license from the original licensor to copy,

distribute or modify the Program subject to these terms and conditions. You

may not impose any further restrictions on the recipients' exercise of the rights

granted herein. You are not responsible for enforcing compliance by third parties

to this License.

7. If, as a consequence of a court judgment or allegation of patent infringement

or for any other reason (not limited to patent issues), conditions are imposed on

you (whether by court order, agreement or otherwise) that contradict the

conditions of this License, they do not excuse you from the conditions of this

License. If you cannot distribute so as to satisfy simultaneously your obligations

under this License and any other pertinent obligations, then as a consequence

you may not distribute the Program at all. For example, if a patent license would

not permit royalty-free redistribution of the Program by all those who receive

copies directly or indirectly through you, then the only way you could satisfy

both it and this License would be to refrain entirely from distribution of the

Program.

If any portion of this section is held invalid or unenforceable under any particular

circumstance, the balance of the section is intended to apply and the section as

a whole is intended to apply in other circumstances.

It is not the purpose of this section to induce you to infringe any patents or other

property right claims or to contest validity of any such claims; this section has

the sole purpose of protecting the integrity of the free software distribution

system, which is implemented by public license practices. Many people have

made generous contributions to the wide range of software distributed through

that system in reliance on consistent application of that system; it is up to the

author/donor to decide if he or she is willing to distribute software through any

other system and a licensee cannot impose that choice.

This section is intended to make thoroughly clear what is believed to be a

consequence of the rest of this License.

8. If the distribution and/or use of the Program is restricted in certain countries

either by patents or by copyrighted interfaces, the original copyright holder who

places the Program under this License may add an explicit geographical

distribution limitation excluding those countries, so that distribution is permitted

only in or among countries not thus excluded. In such case, this License

incorporates the limitation as if written in the body of this License.

9. The Free Software Foundation may publish revised and/or new versions of the

General Public License from time to time. Such new versions will be similar in

spirit to the present version, but may differ in detail to address new problems or

concerns.

Each version is given a distinguishing version number. If the Program specifies a

version number of this License which applies to it and "any later version", you

have the option of following the terms and conditions either of that version or of

any later version published by the Free Software Foundation. If the Program does

not specify a version number of this License, you may choose any version ever

published by the Free Software Foundation.

10. If you wish to incorporate parts of the Program into other free programs

whose distribution conditions are different, write to the author to ask for

permission. For software which is copyrighted by the Free Software Foundation,

write to the Free Software Foundation; we sometimes make exceptions for this.

Our decision will be guided by the two goals of preserving the free status of all

derivatives of our free software and of promoting the sharing and reuse of

software generally.

NO WARRANTY

11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS

NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY

APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE

COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM

"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR

IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF

MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE

ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE

PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE,

YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR

CORRECTION.

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED

TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY

WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS

PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY

GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES

ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM

(INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING

RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD

PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY

OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS

BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

END OF TERMS AND CONDITIONS

---------------------------------------------------------------------------

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.

     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 or perl subroutines supplied by you and linked into this Package shall not

be considered part of this Package.

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.
