Hi all,

I've updated the old hackage-test tool and renamed to hackager.


Hackager is a tool to automate the compiling of all packages on
Hackage. It builds each package on hackage in isolation and records
the results. The purpose being to catch regressions caused by changes
to GHC (and Cabal although this was not the motivation). Two runs of
Hackager can be compared, so the first run is done with a known
version of GHC and the next run with a new, experimental version of
GHC... ect.

The improvements to Hackager over hackage-test are:
* Parallelized the build process. Can now specify how many packages to
build in parallel, which cuts total run time down greatly (e.g 2 days
-> 5 hours)
* hackage-test and hackage-report are now one tool, 'hackager' that
works as a mutli-command tool.
* Proper option handling
* Fixed some stability issues

The new homepage for development can be found here:
