# This is the base Formatter class. Its purpose is to convert
# a content processor's data into specific documents (i.e., table of
# contents, global index, and individual API reference indices).
#
# You need to sub-class it to output anything sensible. For example,
# the file tohtml.py contains the definition of the HtmlFormatter sub-class
# used to output -- you guessed it -- HTML.
