$usage = <<<USAGE

Usage: php find_tested.php [path_to_test_files] ([extension])

Outputs test coverage information for functions and methods in csv format.
Supplying an optional extension name outputs only information for functions and methods from that extension.

Output format:
Extension, Class Name, Method/Function Name, Test Status, Test Files

A test status of "verify" for a method means that there is at least one other method of the same name, so test coverage must be verified manually.
