## upcasing it. You can also normalize everything to lowercase,

## thing to do in the end is probably to find out how to report
## the proper fully-cased package name in our error message.

Some tests of freeze, first we have to install some stuff. Note that
the test is a little crude at the end because Python 2.5+ adds egg
info to the standard library, so stuff like wsgiref will show up in
the freezing. (Probably that should be accounted for in pip, but
currently it is not).
TODO: refactor this test into multiple tests? (and maybe different
test style instead of using doctest output checker)
