Some useful scripts:
check-compiler: test whether the repo compiles warningless
with various compilers.
check-integrity: checks whether everything is svn-added,
the makefiles are correct etc.
release: creates a version numbered release. Is modifies the repository.
DO NOT PLAY WITH IT!

 #!/bin/bash
