tools/dev/all_hll_test.pl - run the test suite for a many of Parrot-dependent projects.
$ perl tools/dev/all_hll_test.pl
This script builds Parrot from the cwd, installs it to a temporary directory and installs/tests a number of HLLs and libraries, storing the output from their builds. Its goal is to provide us with improved assurance that changes made to Parrot won't adversely affect HLLs and libraries without our knowledge.
This program requires installation of the System::Command library from CPAN.
Hopefully an irc bot or some other form of notification will get involved at some point.
