In this appendix, we''ll tell about a little more of what Perl
can do, and give some references on where to learn the details. Some
of what we mention here is on the bleeding edge and may have changed
by the time that you''re reading this book, which is one reason
why we frequently send you to the documentation for the full story.
We don''t expect many readers to read every word of this
appendix, but we hope you''ll at least skim the headings so that
you''ll be prepared to fight back when someone tells you
"You just can''t use Perl for project X, because Perl
can''t do Y."
B.1. Further Documentation
The
documentation that comes with Perl may
seem overwhelming at first. Fortunately, you can use your computer to
search for keywords in the documentation. When searching for a
particular topic, it''s often good to start with the
perltoc (table of contents) and
perlfaq (frequently asked questions) sections.
On most systems, the perldoc command should be
able to track down the documentation for Perl, installed modules, and
related programs (including
perldoc itself).
