Practical Extraction and Report Language.

Perl 5 is a highly capable, feature-rich programming language with over
29 years of development.  Perl 5 runs on over 100 platforms from
portables to mainframes and is suitable for both rapid prototyping
and large scale development projects.

Perl is a language that combines some of the features of C,
sed, awk, and the shell.
