#   W0142 = *args and **kwargs support
# Pointless whinging
#   W0603 = Using the global statement
#   R0201 = Method could be a function
#   W0212 = Accessing protected attribute of client class
#   W0232 = Class has no __init__ method
#   W0212 = Access to a protected member _rev of a client class
# Mistakes in Parsing the AppEngine Source
#   E1103: %s %r has no %r member (but some types could not be inferred)
# Usually makes sense for webapp.Handlers & Friends.
#   W0221 Arguments number differs from %s method
# In Python versions < 2.6 all Exceptions inherited from Exception. py2.6 introduced BaseException
# On AppEngine we do not care much about the "serious" Exception like KeyboardInterrupt etc.
#   W0703 Catch "Exception"
#   R0903 Too few public methods - pointless for db.Models
# Pylint wirft folgenden Fehler nach keinem erkennbaren System.
#   W0404: 24: Reimport 'views.wufoo' (imported line 27)

#   R0924 Badly implemented Container - wtf_forms ist da der Übeltäter
#   R0922 'Abstract class is only referenced 1 times'
# Unused Reports
#   RP0401 External dependencies
#   RP0402 Modules dependencies graph
#   RP0101 Statistics by type
#   RP0701 Raw metrics
