Setup lirc with Xe emulator on mythtv and mythbuntu

If you want to be able to exit Xe using a remote see below.   This can also be modified for use with other emulators as well.

Open a shell and go to ~/.lirc/

Create a new file called xe with the following contents:

#xe
begin
remote = mceusb
prog = irexec
button = Back
config = /home/mondo/killxe
mode = irexec
end

Be sure to substitute your remote type, username, and desired button.  Next, edit ~/.lircrc and add

include ~/.lirc/xe

Create ~/killxe with the following contents:

killall -9 xe
killall -9 irexec

Do 

chmod +x ~/killxe

Edit your emulator startup command inside mythtv.  Add

 irexec&;

before your existing command.
