Hi,

An alternative is to subclass FileHandler with a handler customized for 
your app.

class AppFileHandler(FileHandler):
    def __init__(filename):
       if not os.path.isabs(filename):
          filename = os.path.join(os.environ['APPDATA'], 'whateverdir', 
filename)
       FileHandler.__init__(self, filename, 'w')

[handler_appFileHandler]
class=AppFileHandler
level=DEBUG
formatter=simpleFormatter
args=('foo.log')


It removes the cryptic args=(r'%(logfn)s', 'w') which may puzzle users.


I didn't test the code, it could contain some errors, but you got the idea.
