 """
 TestCommon.py:  a testing framework for commands and scripts
                 with commonly useful error handling
 
 The TestCommon module provides a simple, high-level interface for writing
 tests of executable commands and scripts, especially commands and scripts
 that interact with the file system.  All methods throw exceptions and
 exit on failure, with useful error messages.  This makes a number of
 explicit checks unnecessary, making the test scripts themselves simpler
 to write and easier to read.
