-perldoc - Look up Perl documentation in pod format.
-
-=head1 SYNOPSIS
-
-B<perldoc> [B<-h>] [B<-v>] [B<-t>] [B<-u>] PageName|ModuleName|ProgramName
-
-=head1 DESCRIPTION
-
-I<perldoc> looks up a piece of documentation in .pod format that is
-embedded in the perl installation tree or in a perl script, and displays
-it via pod2man | nroff -man | $PAGER. This is primarily used for the
-documentation for the perl library modules.
-
-Your system may also have man pages installed for those modules, in
-which case you can probably just use the man(1) command.
-
-=head1 OPTIONS
-
-=over 5
-
-=item B<-h> help
-
-Prints out a brief help message.
-
-=item B<-v> verbose
-
-Describes search for the item in detail.
-
-=item B<-t> text output
-
-Display docs using plain text converter, instead of nroff. This may be faster,
-but it won't look as nice.
-
-=item B<-u> unformatted
-
-Find docs only; skip reformatting by pod2*
-
-=item B<PageName|ModuleName|ProgramName>
-
-The item you want to look up. Nested modules (such as C<File::Basename>)
-are specified either as C<File::Basename> or C<File/Basename>. You may also
-give a descriptive name of a page, such as C<perlfunc>. You make also give a
-partial or wrong-case name, such as "basename" for "File::Basename", but
-this will be slower, if there is more then one page with the same partial
-name, you will only get the first one.
-
-=back
-
-=head1 ENVIRONMENT
-
-Any switches in the C<PERLDOC> environment variable will be used before the
-command line arguments. C<perldoc> also searches directories
-specified by the C<PERL5LIB> (or C<PERLLIB> if C<PERL5LIB> is not
-defined) and C<PATH> environment variables.
-(The latter is so that embedded pods for executables, such as
-C<perldoc> itself, are available.)
