alock rXY .. darn, these mercurial commits :)
since the day google announced its support for mercurial on googlecode.com i was looking forward to convert the alock-repository from svn to mercurial. well, actually i looked forward to it even longer.
as today the alock-repository is controlled by mercurial. may the source be with you.
hg clone https://alock.googlecode.com/hg/ alock
have fun!
