This module exports the classes that define a section of a kickstart file.  A
section is a chunk of the file starting with a %tag and ending with a %end.
Examples of sections include %packages, %pre, and %post.

You may use this module to define your own custom sections which will be
treated just the same as a predefined one by the kickstart parser.  All that
is necessary is to create a new subclass of Section and call
parser.registerSection with an instance of your new class.
