There are +three kinds of paragraphs: + +=over 4 + +=item * + +A verbatim paragraph, distinguished by being indented (that is, +it starts with space or tab). It should be reproduced exactly, +with tabs assumed to be on 8-column boundaries. There are no +special formatting escapes, so you can't italicize or anything +like that. A \ means \, and nothing else. + +=item * + +A command. All command paragraphs start with "=", followed by an +identifier, followed by arbitrary text that the command can +use however it pleases. Currently recognized commands are + + =head1 heading + =head2 heading + =item text + =over N + =back + +=item * + +An ordinary block of text. It will be filled, and maybe even +justified. Certain interior sequences are recognized both +here and in commands: + + I<text> italicize text, used for emphasis or variables + B<text> embolden text, used for switches and programs + S<text> text contains non-breaking spaces + C<code> literal code + L<name> A link (cross reference) to name + L<name> manpage + L<name/ident> item in manpage + L<name/"sec"> section in other manpage + L<"sec"> section in this manpage + (the quotes are optional) + F<file> Used for filenames + Z<> A zero-width character + +That's it. The intent is simplicity, not power. I wanted paragraphs +to look like paragraphs (block format), so that they stand out +visually, and so that I could run them through fmt easily to reformat +them (that's F7 in my version of B<vi>). I wanted the translator (and not +me) to worry about whether " or ' is a left quote or a right quote +within filled text, and I wanted it to leave the quotes alone dammit in +verbatim mode, so I could slurp in a working program, shift it over 4 +spaces, and have it print out, er, verbatim. And presumably in a +constant width font. + +In particular, you can leave things like this verbatim in your text: + + Perl + FILEHANDLE + $variable + function() + manpage(3r) + +Doubtless a few other commands or sequences will need to be added along +the way, but I've gotten along surprisingly well with just these. + +Note that I'm not at all claiming this to be sufficient for producing a +book. I'm just trying to make an idiot-proof common source for nroff, +TeX, and other markup languages, as used for online documentation. +Both B<pod2html> and B<pod2man> translators exist. + +=head1 Author + +Larry Wall + |
