 """This is a module for wrapping around python programs and doing some
-minor setup and tear down work for them.  With it, you can break into
-pdb on unhandled top level exceptions, profile your code by passing a
-commandline argument in, audit module import events, examine where
-memory is being used in your program, and so on.
+minor setup and tear down work for them.  With it, you will get:
+
+* The ability to break into pdb on unhandled exceptions,
+* automatic support for :file:`config.py` (argument parsing)
+* automatic logging support for :file:`logging.py`,
+* the ability to enable code profiling,
+* the ability to enable module import auditing,
+* optional memory profiling for your program,
+* ability to set random seed via commandline,
+* automatic program timing and reporting,
+* more verbose error handling and reporting,
+
+Most of these are enabled and/or configured via commandline flags
