NeXT System Administration Release Notes: 
perl

Perl (Practical Extaction and Report Language) is an interpreted language optimized for scanning arbitrary text files, extracting information from those text files, and printing reports based on that information.  It's also a good language for many system management tasks.  

Perl is new in Release 4.0.  Perl documentation is contained in a few dozen UNIX manual pagesÐfor a start, see the overview in perl(1).
