Internal Program Version: IPC::System::Simple  1.300.0.5.42.0

Calling Perl's in-built 'system()' function is easy, determining if it was
successful is _hard_. Let's face it, '?' isn't the nicest variable in the
world to play with, and even if you _do_ check it, producing a
well-formatted error string takes a lot of work.
