Introduction

We use git as our source code repository system. You can access the public git repository for Pygr at http://github.com/cjlee112/pygr. The master branch in our repository represents the main line of Pygr development (i.e. the next release).

Feel free to grab your own copy of the git repository:

git clone git://github.com/cjlee112/pygr.git

However, we recommend you first create an account on github.com, then create a fork of the master git repository in your github.com account. That way, you can easily expose your experimental branches to others, or ask us to incorporate your changes into the master branch (using a github "pull request"). Github provides a lot of great tools for code collaboration. For a quick summary of how we use git, see our page UsingGit. To get git, or learn more information about how to use it, see http://git-scm.com/

Note that we will not be actively using the Subversion repository here at Google Code, at least for the moment. Synchronizing the Google Code subversion server against git proved just to be too flakey.

Github "experimental" branches

Several of us are also using Github to host our own "experimental branches" of Pygr, i.e. code changes that have not yet been chosen for addition to the master branch. Here are links to some of our experimental branch repositories:

• http://github.com/ialbert/pygr-psu/tree/master
• http://github.com/ctb/pygr/tree/master

Nightly tarballs

You can also download nightly tarballs (built from the latest git code) here:
