Specialized option handling.
This module exports three classes:
ExtendAction - A subclass of Action that appends a list of values to an
already existing list. In this way, it's like the existing
"append" action except for lists instead of single values.
ExtendConstAction - A subclass of Action that appends a list of constants
to an already existing list. In this way, it's like the
existing "append_const" action except for lists instead
of single values.
KSOptionParser - A specialized subclass of ArgumentParser to be used
in BaseHandler subclasses.
And it exports two functions:
commaSplit - A function to be used as the type= argument to any arguments
that take a single string that may be split on commas, resulting
in a list of strings.
ksboolean - A function to be used as the type= argument to any arguments
that can take a boolean.

a` Create a new KSOptionParser instance. Each KickstartCommand
subclass should create one instance of KSOptionParser, providing
at least the lineno attribute. version is not required.
Instance attributes:
version -- The version of the kickstart syntax we are checking
against.
