Packaging notions have been removed with the switch to namespaces and PSR-0. The file layout is now one class per file. The only external functions remaining are in misc/misc.php (various helper functions), and misc/psr0.php (sample autoloader).

• package: fsm
• subpackage
  • fsm.ui
    • Background_Application.php: enables PHP-GTK applications to run FSM-controlled actions, notably background processing which does not freeze the UI
    • Fsm_From_Dia.php: class to convert Dia UML diagrams to FSM XML files using Fsm_Writer
    • dia2fsm.php: command-line tool using Fsm_From_Dia to perform the Dia UML to FSM conversion
  • fsm.core
    • Finite_State_Machine.php: abstract read-only FSM, to be used by most applications
      • Fsm_Result: private class in Finite_State_Machine.php, to hold FSM processing results
    • Fsm_Writer.php: read-write FSM, derived from Finite_State_Machine and able to create FSM files, to be used by FSM creation tools like dia2fsm
