+exceptions
+==========
+dsm.playPrompt, dsm.playFile, dsm.recordFile and dsm.setPromptSet
+may throw an exception. This is a Python RuntimeError exception,
+not the DSM exception handling (exceptions in interpreted code
+can not be catched through outside of the interpreter).
+The application needs to catch the exceptions in the python code
+itself, and can then handle them or signal the DSM code to throw
+an exception. example:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+initial state begin
+ enter {
+ py(dsm.INFO("hello dsm-world\n"))
+ py(#
+try:
+ session.playFile('doesnotexist.wav')
+except RuntimeError, e:
+ dsm.ERROR('thats a runtime error: ' + e.message + '!\n')
+ session.setvar('exception', e.message)
+)
+ log(2, huhu, still there);
+ repost();
+};
+transition "catch py exception" begin - test($exception!="") /
throw($exception) -> begin;
+transition "normal exception handling" begin - exception; test(#type=="file")
-> exception_state;
