 The files in this directory are called by autopkgtest in the debian package but can be used by any packager to verify installed packages. Each test-* script should be run from the top of the source tree and takes an empty directory as its single argument. The test passes if the script exits with a zero exit status. Note that these tests write to stderr because they use set -x in the shell.
