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. In fact, if you
want to be really lazy, you can just write:
use IPC::System::Simple qw(system);
and all of your "system" commands will either succeed (run to completion and
return a zero exit value), or die with rich diagnostic messages.
