-def catches(catch=None, handler=None, exit=True):

-    Very simple decorator that tries any of the exception(s) passed in as
-    a single exception class or tuple (containing multiple ones) returning the
-    exception message and optionally handling the problem if it rises with the
-    handler if it is provided.
-
-    So instead of douing something like this::
-
-        def bar():
-            try:
-                some_call()
-                print "Success!"

-                print "Error while handling some call: %s" % exc
-                sys.exit(1)
-
-    You would need to decorate it like this to have the same effect::
-
-        @catches(TypeError)
-        def bar():
-            some_call()
-            print "Success!"
-
-    If multiple exceptions need to be catched they need to be provided as a
-    tuple::
-
-        @catches((TypeError, AttributeError))
-        def bar():
-            some_call()
-            print "Success!"
