perlpod - the Plain Old Documentation format
Pod is a simple-to-use markup language used for writing documentation for Perl, Perl programs, and Perl modules.
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.
Most paragraphs in your documentation will be ordinary blocks of text, like this one. You can simply type in your text without any markup whatsoever, and with just a blank line before and after. When it gets formatted, it will undergo minimal formatting, like being rewrapped, probably put into a proportionally spaced font, and maybe even justified.
You can use formatting codes in ordinary paragraphs, for bold, italic, code-style, hyperlinks, and more. Such codes are explained in the "Formatting Codes" section, below.
Verbatim paragraphs are usually used for presenting a codeblock or other text which does not require any special parsing or formatting, and which shouldn't be wrapped.
A verbatim paragraph is distinguished by having its first character be a space or a tab. (And commonly, all its lines begin with spaces and/or tabs.) It should be reproduced exactly, with tabs assumed to be on 8-column boundaries. There are no special formatting codes, so you can't italicize or anything like that. A \ means \, and nothing else.
A command paragraph is used for special treatment of whole chunks of text, usually as headings or parts of lists.
All command paragraphs (which are typically only one line long) start with "=", followed by an identifier, followed by arbitrary text that the command can use however it pleases. Currently recognized commands are
