<pre>GETTING HELP
The perldoc program gives you access to all the documentation that comes
with Perl. You can get more documentation, tutorials and community
support online at <http://www.perl.org/>.
If you're new to Perl, you should start by running "perldoc perlintro",
which is a general intro for beginners and provides some background to
help you navigate the rest of Perl's extensive documentation. Run
"perldoc perldoc" to learn more things you can do with perldoc.
For ease of access, the Perl manual has been split up into several
sections.
