\t$0 post-build

If you use »git buildpackage« you can leave these alone as they will
be run at the right places auto-magically. Otherwise you should use
»pre-export« to update po and pot files as well as version numbering.
»post-build« can be used to run some more or less useful checks later on.

\t$0 library
\t$0 buildlog filename…

»library« and »buildlog« aren't run automatically but can be useful for
maintaining the (more or less experimental) symbols files we provide.
»library« displays the diff between advertised symbols and the once provided
by the libraries, while »buildlog« extracts this diff from the buildlogs.
Both will format the diff properly.

\t$0 travis-ci
\t$0 coverage [output-dir]

»travis-ci« is a shortcut to install all build- as well as test-dependencies
used by .travis.yml.
»coverage« does a clean build with the right flags for coverage reporting,
runs all tests and generates a html report in the end.
