Unix: Perl 5.005_03 is installed in Kellogg's research Unix server, skew3.
Windows: Active Perl is available for installation in workstations running Microsoft Windows, Solaris and Linux.
"Perl" is an acronym for "Practical Extraction and Report Language". It is a language for processing text, derived from C, sed, awk, and the Unix shells.
Perl is Open Source software. It can be downloaded from several sites. See the links below.
There are numerous perl user lists and news groups:

Users creating perl scripts must be careful in specifying the location of the perl interpreter. In skew3, the interpreter is in "/usr/local/bin/perl". Thus, the first line in the script should be #!/usr/local/bin/perl. Scripts in skew can be executed by typing "perl scriptname" at the command line or by making the script executable (with the chmod command).
In other Unix hosts, the location of the perl command interpreter can be determined with the whereis command (whereis perl).
See Kellogg's online program samples .
There are sample scripts in CPAN and other archives.
For documentation in skew, check the Perl manual pages (man perl). The installation of Active Perl in a workstation will include documentation in HTML format.
