Description: Allow tests of command-line tools to be skipped
 The test suite has no clean separation between testing the command line tools
 and testing the classes; the packaging will end up separating them, making
 in-place testing of only the modules difficult. This patch adds an environment
 variable to disable command-line tools being called from tests.
