Kernel::System::ProcessManagement::TransitionAction - action lib

=head1 DESCRIPTION

All Process Management Transition Action functions.

=head1 PUBLIC INTERFACE

=head2 new()

Don't use the constructor directly, use the ObjectManager instead:

=head2 TransitionActionGet()

    Get transition action info
