Matthew, As you no doubt realised that text is read straight from the
Features.txt file. PyPI interprets it as RestructuredText, which uses
\ as an escape character in various cases. Do you intentionally write
Features.txt as RestructuredText? If so here is a patch that escapes
the \ characters as appropriate, otherwise I'll work out how to make
PyPI read it as plain text.

Regards, Alex
