Testsuite for hpc-lib also tests hpc-bin
The testsuite for hpc-lib (this repository) contains tests which check the output of the hpc binary (currently in the main ghc repository); it shouldn't.
hpc-the-binary is a consumer of hpc-the-library, and the latter shouldn't be so closely coupled to the former in its testsuite. The responsibility of hpc-the-library is to parse and print tix/mix files. It shouldn't also verify the html output of hpc-the-binary, for example.
