move(src, dst)

source code 

Recursively move a file or directory to another location.

If the destination is on our current filesystem, then simply use rename. Otherwise, copy src to the dst and then remove src. A lot more could be done here... A look at a mv.c shows a lot of the issues this implementation glosses over.

rmtree(rootdir)

source code 
Catch shutil.rmtree failures on Windows when files are read-only. Thanks Google!

read_policy_content(filename)

source code 
Read the policy number from the policy file. strict allows to activate the new policy scanning.

guess_encoding(data)

source code 

Given a byte string, guess the encoding.

First it tries for UTF8/UTF16 BOM.

Next it tries the standard 'UTF8', 'ISO-8859-1', and 'cp1252' encodings, Plus several gathered from locale information.

The calling program must first call locale.setlocale(locale.LC_ALL, '')

If successful it returns (decoded_unicode, successful_encoding) If unsuccessful it raises a UnicodeError.

This was taken from http://www.voidspace.org.uk/python/articles/guessing_encoding.shtml

touch(srcdir)

source code 
Recursively touches all the files in the source path mentioned. It does not touch the directories.
