1 Calling Perl's in-built system() function is easy, determining if
2 it was successful is hard.
3 Let's face it, $? isn't the nicest variable in the world to play with,
4 and even if you do check it, producing a well-formatted error string
5 takes a lot of work.
7 IPC::System::Simple takes the hard work out of calling external commands.
8 In fact, if you want to be really lazy, you can just write:
10 use IPC::System::Simple qw(system);
12 and all of your system commands will either succeed (run to completion
13 and return a zero exit value), or die with rich diagnostic messages.
