JRel's source code is hosted in a Mercurial repository. Mercurial is a fast, lightweight and powerful distributed source code management system.
To checkout the code, install Mercurial (see link above) and enter the following from your command line:
hg clone http://www.thimbleware.com/hg/jrel
To view the repository online you can use either the Trac Browse Source functionality or the hosted Mercurial repository web tool. Both provide functions such as repository history, revision diffs, RSS feeds, etc.
The ability to checkin (push) code to the repository is available on request. If you want to contribute, please contact [Ryan Daum, the project maintainer.
