Phabricator
Installing Phabricator is as simple as any other LAMP installation. We grabbed the three primary git repos, here:
m@bitpost cd development/phabricator git clone https://github.com/phacility/libphutil.git git clone https://github.com/phacility/arcanist.git git clone https://github.com/phacility/phabricator.git
Then set up an alias and directory in apache. Then a mysql user + db. Browse to the url to finish. Easy peasy.
Phabricator API can be used to extract a query of tasks, for inclusion on bitpost.com, for example. See bitpost.com code for details.
