Driver Engine		This Perl-based driver reads the input test files, processes the test records within the specified input file, and declares each test performed as either a pass or a fail. Counts are kept recording the number of passes and failures.
Input Test File		The input test file is a collection of one-line test records processed in a sequential manner. Each record includes identifying information (e.g., a test number and description), the test to be performed, and the criteria required to declare a pass. The test may be a parameter-based call to the one of the test plugins or it may contain an actual environment-specific command that will be passed to the OS for execution.
Test Plugins		A test plugin is a modular block of code that performs a single function. The plugin serves as the actual interface between the test driver and the OS being evaluated. The plugin converts the test to the native OS for processing.
