wyvie [1] filed a deletion request for beaker [2]:
It's so out of date that it's actually completely unuseable,
unbuildable (as some dependencies are), actual version is 24.3.
I will package the actual beaker client only as soon as dev releases
the sphinxcontrib-httpdomain (which is currently broken and doesn't
work with up-do-date sphinx).
