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.
'IPC::System::Simple' takes the hard work out of calling external
commands.
