 To get truly stand-alone applications, the Tcl scripts that form the library
 have to be integrated into the application as well. One tool supporting that is
 SAM (stand-alone modules), which is part of the Tix distribution

 Can I have Tk events handled while waiting for I/O?
 ---------------------------------------------------
 
 Yes, and you don't even need threads!  But you'll have to restructure your I/O
-code a bit.  Tk has the equivalent of Xt's XtAddInput() call, which allows you

 to register a callback function which will be called from the Tk mainloop when
 I/O is possible on a file descriptor.  Here's what you need::
