AppPkg/Applications/Python: Add Python 2.7.2 sources since the release of Python 2.7.3 made them unavailable from the python.org web site.
These files are a subset of the python-2.7.2.tgz distribution from python.org. Changed files from PyMod-2.7.2 have been copied into the corresponding directories of this tree, replacing the original files in the distribution.

"""File System Proxy.
|
||||
|
||||
Provide an OS-neutral view on a file system, locally or remotely.
|
||||
The functionality is geared towards implementing some sort of
|
||||
rdist-like utility between a Mac and a UNIX system.
|
||||
|
||||
The module defines three classes:
|
||||
|
||||
FSProxyLocal -- used for local access
|
||||
FSProxyServer -- used on the server side of remote access
|
||||
FSProxyClient -- used on the client side of remote access
|
||||
|
||||
The remote classes are instantiated with an IP address and an optional
|
||||
verbosity flag.
