PageName|ModuleName...
is the name of a piece of documentation that you want to look at. You
may either give a descriptive name of the page (as in the case of
`perlfunc') the name of a module, either like `Term::Info' or like
`Term/Info', or the name of a program, like `perldoc'.
BuiltinFunction
is the name of a perl function. Will extract documentation from
`perlfunc'.
FAQRegex
is a regex. Will search perlfaq[1-9] for and extract any
questions that match.
Any switches in the PERLDOC environment variable will be used before the
command line arguments. The optional pod index file contains a list of
filenames, one per line.

Translators are available for converting Pod to various formats like
plain text, HTML, man pages, and more.
Pod markup consists of three basic kinds of paragraphs: ordinary,
verbatim, and command.
