Originally, versions v1.4.5, v1.4.6, and v1.4.7 of the JAM library code originally by Björn Stenberg was imported into a CVS repository here; that repository is still available but it was migrated to a GIT repository where all current development work is now done, in particular for JAMLIB Debian/Ubuntu packaging.

Branches planned to be in the GIT repository:

Branch	Remarks
master	Master branch for the JAM Libary code
debian	Integration branch for Debian packaging. Includes the debian directory and the jamlib code merged from the master branch.
pristine-tar	pristine-tar data for recreating tar.gz archives from directly from the repository.

Johan Billing has a mercurial repository for version v1.3.2, which also includes a fix he backported from v1.4.7.
