The Practical Extraction and Reporting Language (Perl), has grown to be
one of the most powerful and popular scripting languages. Combining the
best features of C, UNIX utilities, and regular expressions, these days
Perl is used for an array of tasks, including system administration,
text processing and Web programming. Recently, it's been used for more
exotic areas like bioinformatics. Perl is supported by all of the most
prominent operating systems, including Windows, Unix, OS/2, Amiga, and
others.
