The qtqa module contains our test scripts used in CI.  It is critical
that these scripts themselves have a complete and regularly executed
test suite, otherwise there is no safety net preventing the pushing of
completely broken test scripts breaking CI for all Qt modules.

  setup.pl: install all needed perl and python modules for the qtqa test
  scripts.  Should be run as the first part of any test procedure which
  uses the qtqa scripts.

  test.pl: run all selftests for the qtqa test scripts.  Called by
  `make check'.
