copyleft.org
============

copyleft.org is a collaborative project to create and disseminate useful
information, tutorial material, and new policy ideas regarding all forms of
copyleft licensing.

### The Copyleft Guide and Tutorial

The primary project currently on this site is a tutorial book entitled
[*Copyleft and the GNU General Public License: A Comprehensive Guide and Tutorial*](/guide/).
This guide describes the policy motivations for copyleft, presents a detailed analysis of the text of
various copyleft licenses, and gives examples and case studies of copyleft compliance situations.

### Getting Involved

There are various ways to get involved with this project.  The primary
copyleft.org website is a wiki, and we welcome helpful edits and additions.

For the aforementioned guide and tutorial about GPL and other copyleft concepts,
we seek help in the following ways:

#### Proposing Improvements to the Guide

[Merge requests on copyleft.org's gitorious site](https://gitorious.org/copyleft-org/tutorial/merge_requests)
to the Guide are most welcome. If you're looking for something to fix, just
grep the *.tex files for "FIXME" and you'll find plenty.  Many of them are
simple and easy to do.  Some of them are writing, and some of them are
formatting-related.

#### Joining Mailing Lists

   * Subscribe to our low-traffic [announcements-only mailing list](https://lists.copyleft.org/cgi-bin/mailman/listinfo/announce).
   * Join discussion on our [primary mailing list, called "discuss"](https://lists.copyleft.org/cgi-bin/mailman/listinfo/discuss).

#### IRC Discussion

The coypleft.org
[IRC channel is #copyleft on irc.freenode.net](irc://irc.freenode.net/#copyleft).
The [IRC logs are public here on this site](/irclogs/).

### Who Contributes to copyleft.org?

This site is a joint project of
[Software Freedom Conservancy](https://sfconservancy.org) and the

### URLs You Can Memorize!

copyleft.org has many easy-to-remember URLs.  These are convenience URLs that
you can memorize and give to people verbally to point them to the right part
of [The Guide](https://copyleft.org/guide/).  (Since the guide is very large,
we thought a few easy-to-remember ways to tell people where to look would be
helpful.)  Here are the primary ones:

  * [copyleft.org](https://copyleft.org) points to this page.
  * [copyleft.guide](http://copyleft.guide) points to the guide itself.
  * [compliance.guide](http://compliance.guide) points to the *GPL Compliance Guide* section of the full Guide.
  * [gpl.guide](http://gpl.guide) points to the *Detailed Analysis of the GNU GPL and Related Licenses* section of the full Guide.

As time goes on, we'll add convenience URLs to refer to specific parts of the
guide, which makes it easy to refer people to portions of the Guide.  Here
are a the ones that exist so far:

  * [compliance.guide/pristine](http://compliance.guide/pristine) points to
    the "pristine example", the chapter entitled *ThinkPenguin Wireless Router: Excellent CCS*.
