Thank you!

I shortened the description a bit while adding @code{} notations where
appropriate, and also added a copyright statement for you.  Hope that

I also moved the package so it wasn't squeezed between the Python3 and
Python2 variants of python-py-bcrypt.

(...and closing the previous patch bug while at it...)
