I don't know about OS X, but on Windows Vista and later, there is
os.environ['APPDATA']. I don't explicitly check for OS; instead, I see if
APPDATA exists as an environment variable:
try:
user_data_dir = os.path.join(os.environ['APPDATA'], 'NoiseBot')
except KeyError:
user_data_dir = os.path.join(os.environ['HOME'], '.NoiseBot')
I didn't even know that such a thing existed on OS X.
