This caused normal installs (i. e. without --editable) of this library
to not include the rsrcfork.compress subpackage, and made everything
unusable as a result. Oops.
Altough this library is OS-independent, it is specifically relevant to
Classic Mac OS and OS X, and provides some extra functionality on OS X
(reading actual resource forks, instead of resource fork data stored in
data forks/regular files).
"Topic :: Software Development :: Libraries :: Python Modules" appears
to be specifically for libraries used to develop Python modules, and
not for Python modules in general. A few more appropriate classifiers
have been added instead.
