One +VERY serious one is that there is no real documentation. You just have +to see the existing tests.

The third serious problem is that it's not relocatable: the only +way it works when you build out of the source tree is to create +symlinks, which doesn't work on every system and is bogus to boot. The +fourth serious problem is that it doesn't create its own sandbox when +running tests, so that if a test forgets to clean up after itself that +can impact future tests. + +The test suite requires Perl.
