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.

The
+builtin open function is defined in this module.
+
+At the top of the I/O hierarchy is the abstract base class IOBase. It
+defines the basic interface to a stream. Note, however, that there is no
+separation between reading and writing to streams; implementations are
+allowed to throw an IOError if they do not support a given operation.
+
+Extending IOBase is RawIOBase which deals simply with the reading and
+writing of raw bytes to a stream. FileIO subclasses RawIOBase to provide
+an interface to OS files.
+
+BufferedIOBase deals with buffering on a raw byte stream (RawIOBase). Its
+subclasses, BufferedWriter, BufferedReader, and BufferedRWPair buffer
+streams that are readable, writable, and both respectively.
+BufferedRandom provides a buffered interface to random access
+streams. BytesIO is a simple stream of in-memory bytes.
+
+Another IOBase subclass, TextIOBase, deals with the encoding and decoding
+of streams into text. TextIOWrapper, which extends it, is a buffered text
+interface to a buffered raw stream (`BufferedIOBase`). Finally, StringIO
+is a in-memory stream for text.
+
+Argument names are not part of the specification, and only the arguments
+of open() are intended to be used as keyword arguments.
+
+data:
+
+DEFAULT_BUFFER_SIZE
+
+ An int containing the default buffer size used by the module's buffered
+ I/O classes. open() uses the file's blksize (as obtained by os.stat) if
+ possible.
+"""
+# New I/O library conforming to PEP 3116.
+
+# XXX edge cases when switching between reading/writing
+# XXX need to support 1 meaning line-buffered
+# XXX whenever an argument is None, use the default value
+# XXX read/write ops should check readable/writable
+# XXX buffered readinto should work with arbitrary buffer objects
+# XXX use incremental encoder for text output, at least for UTF-16 and UTF-8-SIG
+# XXX check writable, readable and seekable in appropriate places
