4. State of Perl
Two types of programmers use Perl. System administrators like it for the way
it glues together system commands to manipulate data and processes, and for its
pattern-matching functions aids in system searches and reporting. People
developing electronic forms for Unix Web servers find Perl easier to learn and
use than C, and for their purposes Perl offers more built-in or publicly
available functions such as easy data validation and simple databases.
The Perl code in this document works under both Perl 4.x and Perl 5.x. Perl 5 added object-oriented facilities and
other conveniences. The Reference Guide identifies with a double-dagger (as in
++) new features of Perl 5.
For major general-purpose Perl applications, particularly CGI scripts and
client or server applications, first check the 'Net for Perl modules that you
can exploit! See the FAQ "Perl 5 Module List" regularly posted to the Usenet
