From f9b458c88b83b60004b97b112bc46365406726bd Mon Sep 17 00:00:00 2001

Subject: For PR747: If we fail to find a required program, simply set that
 program to echo out something that tells the user the situation. That is,
 instead of just "true runtest" we now get "echo 'Skipped: runtest not
 found'".
