\t$0 pre-build
\t$0 post-build

Updating po-files and versions as well as some basic checks are done
by »pre-export« which needs to be run before package building.
If you use »gbp buildpackage« you will be notified if you forget.
»pre-build« and »post-build« can be used to run some more or less
useful checks automatically run by »gbp« otherwise.

\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 in .gitlab-ci.yml and other CI infrastructure.
»coverage« does a clean build with the right flags for coverage reporting,
runs all tests and generates a html report in the end.

\t$0 spellcheckers

»spellcheckers« runs »codespell« and »spellintian« on the appropiate files and
filters out obvious false positives.

\t$0 merge-translations branch

Merge translations from the given branch.
