Documentation does not match due to version number inconsistency.

Current:
< Then the following directories are added to sys.path, in this order:
<
<
< /usr/local/lib/python2.3/site-packages/bar
< /usr/local/lib/python2.3/site-packages/foo

Proposed:
> Then the following directories are added to sys.path, in this order:
>
>
> /usr/local/lib/python{X.Y}/site-packages/bar
> /usr/local/lib/python{X.Y}/site-packages/foo

Syntax for proposed documentation fix may be incorrect, but this gives 
the general idea anyway...
