Git is open source and readily available to all Perl developers. Among other advantages, the announcement notes that git simplifies commits, producing fewer administrative overheads for integrating contributions. Git's change analysis tools are also singled out for praise.
The transformation from Perforce to git apparently took over a year. Sam Vilain of Catalyst IT "spent more than a year building custom tools to transform 21 years of Perl history into the first ever unified repository of every single change to Perl." The git repository incorporates historic snapshot releases and patch sets, which is frankly both cool and historically pleasing. Some of the patch sets were apparently recovered from old hard drives, notching up the geek satisfaction factor even more.
Developers can download a copy of the current Perl 5 repository directly from the perl.org site, where the source is hosted."
