"""
Implement output filters to print kernel-doc documentation.

The implementation uses a virtual base class (OutputFormat) which
contains dispatches to virtual methods, and some code to filter
out output messages.

The actual implementation is done on one separate class per each type
of output. Currently, there are output classes for ReST and man/troff.
