[Danny Nicholas]

Guess you hate me about half the time :).  Gonna try mfe.c with 1.4.

I hate it when people post about things they know nothing about...

So I wrote My First ExternalIVR (mfe.c). I'm a 1.2 Luddite, so things may 
be a bit different for the Asterisk version you are using. Comparing the 
documentation, it looks like a lot of useful commands have been added.

The first question I had was "Where do you put the executable?" The 
documentation is silent on this point. ASTAGIDIR seemed a likely guess. 
Guess not. It looks like it has to be an absolute path. Inconvenient, but 
it works.

The actual protocol is trivial, way "simpler" and limited than AGI.

Here's a snippet that shows how to play a file and then "handle" the key 
press events.

// play a file
         printf("S,demo-congrats\n");
         fflush(stdout);

// read events
         while   (NULL != fgets(event, sizeof(event), stdin))
                 {
                 syslog(LOG_ERR, event);
                 if      ('#' == *event)
                         {
                         break;
                         }
                 }
