 An interpreted scripting language, known among some as "Unix's Swiss
 Army Chainsaw".
 .
 Perl is optimised for scanning arbitrary text files and system
 administration. It has built-in extended regular expression matching
 and replacement, a data-flow mechanism to improve security with
 setuid scripts and is extensible via modules that can interface to C
 libraries.
