Perl is one of the few truly great marvels - an extremely fast interpreted language that is free and available on a wide range of computer platforms. It comes as standard on most Unix and Linux distributions, and can be installed on Windows and even DOS

Scripts that I have written include:

An 'include' routine that does the same as the SSI include virtual directive, but includes error checking and limitations to the file locations it will use

A password generator to produce passwords that are difficult to break with dictionary attacks. Not necessarily easy to remember though!
