The Paper Tape Project -- Punching subsystem
 ============================================
 
 The punching subsystem consists of platform independent frontend programs and
 platform dependent backend library calls.

 The frontends
 -------------
 There are currently two frontends:
 
 * gtk-frontend.c: This one uses the GtkPaperTape GTK widget to display the
   paper tape file which is currently punched. Additionaly it displays widgets
   to control the punching cycle.

   TODO -- PLANNED FEATURES:
     * Nicer GUI
     * Open/Close Paper Tape Files
     * Statistical details
     * Generate zero bytes at front/end of files
     * Generate paper tape label
     * Generate label-only paper tape files

 * puncher-frontend.pl: A simple interactive CLI Perl frontend to punch a paper tape
   file with a label which the user types in on STDIN.

 The backends
 ------------
 There is already an existing ppdev driver for Linux. It is planned to program a driver
 with the same facilities for Microsoft Windows NT (Windows 2000/XP). 

 * puncher.[platform].c: The file which implements punching routines.

 The backends have not been programmed yet.
