Perl

Perl /perl/ n.  [Practical Extraction and Report Language,
   a.k.a Pathologically Eclectic Rubbish Lister] An interpreted
   language developed by Larry Wall <lwall@jpl.nasa.gov>, author
   of `patch(1)' and `rn(1)') and distributed over Usenet.
   Superficially resembles {awk}, but is much hairier, including
   many facilities reminiscent of `sed(1)' and shell and a
   comprehensive UNIX system-call interface.  UNIX sysadmins, who are
   almost always incorrigible hackers, increasingly consider it one of
   the {languages of choice}.  Perl has been described, in a parody
   of a famous remark about `lex(1)', as the "Swiss-Army
   chainsaw" of UNIX programming.
