The main repository is using git, but that doesn't mean you have to use it since we provide mirrors of the repository in other version control systems.
You can browse the code on Launchpad or check the code out locally:
git clone https://git.launchpad.net/~libravatar/libravatar
A mirror of it is also available on Github.
Otherwise, just clone the repo:
hg clone https://bitbucket.org/libravatar/libravatar
Using other version control systems
Is your favourite source control system not in our list? Well, if you can send us instructions on how to convert a git repository to a YourFavoriteVCS repository, then we'll try to add it to the sync cronjob we have.
