os.path would be more idiomatic. comment not very useful in its current form,
but if you mentioned that it was so that path validity checks pass... that would
be usefu.

os.path.split() is not the inverse of os.path.join() (only extracts path &
filename, rather than extract components).

I tried posixpath, and that didn't convert '\\' to '/'.

I found the code using .replace(os.sep, '/') elsewhere in this directory, so
using that.

bleh, I meant os.sep not os.path.
