Common operations on Posix pathnames.
Instead of importing this module directly, import os and refer to this
module as os.path. The "os.path" name is an alias for this
module on Posix systems; on other systems (e.g. Mac, Windows), os.path
provides the same operations in a manner specific to that platform, and
is an alias to another module (e.g. macpath, ntpath).
Some of this can actually be useful on non-Posix systems too, e.g. for
manipulation of the pathname component of URLs.
