class PyLockfile(PythonPackage):
"""The lockfile package exports a LockFile class which provides a
simple API for locking files. Unlike the Windows msvcrt.locking
function, the fcntl.lockf and flock functions, and the
deprecated posixfile module, the API is identical across both
Unix (including Linux and Mac) and Windows platforms. The lock
mechanism relies on the atomic nature of the link (on Unix) and
mkdir (on Windows) system calls. An implementation based on
SQLite is also provided, more as a demonstration of the
possibilities it provides than as production-quality code.
