Practical Extraction and Report Language
-or- Pathologically Eclectic Rubbish Lister
From the Wikipedia:
Perl is a dynamic programming language created by Larry Wall and first released in 1987. Perl borrows features from a variety of other languages including C, shell scripting (sh), AWK, sed and Lisp.
Structurally, Perl is based on the brace-delimited block style of AWK and C, and was widely adopted for its strengths in string processing, and lack of the arbitrary limitations of many scripting languages at the time.

Persistence for Perl data structures. Save's a lot of nitpicking with reading and writting files that's don't need to be accessed by anything else then a perlscript e.g. temporary data for CGI's and daemons.
Net::LDAP
A very comprehensive way to work with Lightweight Directory Access Protocol
Sys::Syslog
Perl interface to the UNIX syslog(3) calls. Why bother writting and maintaining logfiles when someones else can do it?
Spreadsheet::WriteExcel
Very easy way to generate excelsheets for e.g. reporting.
