This extension adds signal handling to Tcl/Tk scripts.
It has only been tested under Unix.

To ensure that signal handling does _not_ happen asynchronously,
and only occurs in the X loop, the signal handler writes the
signal number on a pipe, which is handled through the Tcl
file handling mechanism (like XtAppAddInput in X).
