Bear in mind that Perl’s system() call is similar to the ANSI C version —i.e.
its return value is encoded as with wait(2). To get the ‘real’ exit code of the
program you’ve called, you need to do some additional processing — it is *not*
enough merely to look for a non-zero return to signal an error. See:
http://perldoc.perl.org/functions/system.html
