-"""FoundationPlist.py -- a tool to generate and parse MacOSX .plist files.
-
-This is intended as a drop-in replacement for Python's included plistlib,
-with a few caveats:
- - readPlist() and writePlist() operate only on a filepath,
- not a file object.
- - there is no support for the deprecated functions:
- readPlistFromResource()
- writePlistToResource()
- - there is no support for the deprecated Plist class.
-
-The Property List (.plist) file format is a simple XML pickle supporting
-basic object types, like dictionaries, lists, numbers and strings.
-Usually the top level object is a dictionary.
-
-To write out a plist file, use the writePlist(rootObject, filepath)
-function. 'rootObject' is the top level object, 'filepath' is a
-filename.
-
-To parse a plist from a file, use the readPlist(filepath) function,
-with a file name. It returns the top level object (again, usually a
-dictionary).
-
-To work with plist data in strings, you can use readPlistFromString()
-and writePlistToString().
