libipc-system-simple-perl 1.18-1 (i386 binary) in ubuntu lucid

 Calling Perl's in-built system() function is easy,
 determining if it was successful is hard.
 .
 IPC::System::Simple takes the hard work out of calling external commands; all
 of your system() commands will either succeeed (run to completion and return
 a zero exit value), or die with rich diagnostic messages.
