oslex is an OS-independent wrapper for shlex and mslex.
Its main purpose is to provide functions similar in functionality to shlex.quote(), shlex.split() and shlex.join() on both Windows and POSIX-compatible platforms.
This goal is achieved by simply forwarding the calls to either shlex (from the standard library) on POSIX-compatible systems, or the excellent mslex library (written by Lawrence D'Anna / @smoofra) on Windows.
In other words, oslex is to shlex/mslex what os-path is to posixpath/ntpath.
This library itself is licensed under the MIT license.
oslex uses the mslex library, which is distributed under the Apache 2.0 license.
