"""biplist -- a library for reading and writing binary property list files.

Binary Property List (plist) files provide a faster and smaller serialization
format for property lists on OS X. This is a library for generating binary
plists which can be read by OS X, iOS, or other clients.

The API models the plistlib API, and will call through to plistlib when
XML serialization or deserialization is required.

To generate plists with UID values, wrap the values with the Uid object. The
value must be an int.

To generate plists with NSData/CFData values, wrap the values with the
Data object. The value must be a string.

Date values can only be datetime.datetime objects.

The exceptions InvalidPlistException and NotBinaryPlistException may be
thrown to indicate that the data cannot be serialized or deserialized as
a binary plist.

Plist generation example:

    from biplist import *
    from datetime import datetime
    plist = {'aKey':'aValue',
             '0':1.322,
             'now':datetime.now(),
             'list':[1,2,3],
             'tuple':('a','b','c')
             }
    try:
        writePlist(plist, "example.plist")
    except (InvalidPlistException, NotBinaryPlistException), e:
        print "Something bad happened:", e

Plist parsing example:

    from biplist import *
    try:
        plist = readPlist("example.plist")
        print plist
    except (InvalidPlistException, NotBinaryPlistException), e:
