of the PyUNIT version of the same file.  This helps people understand that
this version is the same as the version from the independent PyUNIT
release (confusion was indicated on the PyUNIT mailing list).

 - Adds Fred's patch 487662: "Better error message for assertEqual"
 - Removed small portion of code unused after Guido's patch
   490119: "Don't treat ^C as error"

annoying that often you have to hit ^C numerous times before it
works.  The solution: before the "except:" clause, insert "except
KeyboardInterrupt: raise".  This propagates KeyboardInterrupt out,
stopping the test in its tracks.

    Don't put paren in column 0 (to please font-lock mode).
    Put space after comma in argument list.

(Steve, can you add this to the PyUnit repository as well?)

This patch is similar to that proposed by Jeremy. The proposed patch altered
the interface of TestResult such that it would be passed the error
information as a string rather than an exc_info() tuple.

The implemented change leaves the interface untouched so that TestResults
are still passed the tracebacks, but stor them in stringified form for
later reporting.

Notes:
- Custom subclasses of TestResult written by users should be unaffected.
- The existing 'unittestgui.py' will still work with this module after the
  change.
- Support can later be added to pop into the debugger when an error occurs;
  this support should be added to a TestRunner rather than to TestCase itself,
  which this change will enable.

(Jeremy, Fred, Guido: Thanks for all the feedback)

If 'unittest.py' was run from the command line with the name of a test
case class as a parameter, it failed with an ugly error. (Which was a
shame, because the documentation says you can do that.)

The problem was the old 'is the class X that you imported from me the same
as my class X?' gotcha.

- Removed unused variable 'opts' in TestProgram.__init__ (thanks to PyChecker)

- TestCase.failureException defines the exception that indicates a test failure
- Docstrings for TestLoader class
- Added exc_info() hack back in

* Fixed TestLoader.loadTestsFromName() for nested packages
* Corrected the command-line usage summary

changed accordingly.
