Well, ppt used to be cool, but the project seems to be sleeping now... and anyway the purpose here is not to show how to reimplement possibly complex *NIX commands in Perl, but just the reverse: to show how things a newbie may want to system (or similar) out to an external program to do can be handled just fine with basic perl construct or judicious use of a core or CPAN module.
