# The add() method defined in django-taggit's _TaggableManager causes an       #
# infinite loop when an existing tag is 'added' again with a different         #
# combination of upper and lower case letters. Because the logic that looks    #
# for existing tags is in add() case-sensitive, whereas LowerCaseTag's save()  #
# method is not, the same tag is always considered new causing a World of      #
# Hurt.                                                                        #

# Monkey patching our Topic's tag manager proved to be infeasible, hence       #
# the two Manager classes below. The only difference from the original         #
# django-taggit code is that the tags in add() are all lower-cased, and that   #
# _TaggableManager is replaced with _LowerCaseTaggableManager in __get__().    #
