What you're looking for is the verbatim environment. It's similar to <code>...</code> in HTML and is written like this:

\begin{verbatim}
#!/usr/bin/perl

for (1..10) {
    print "Hello, world\n";
}
\end{verbatim}
[download]

The result would look like this:

#!/usr/bin/perl

for (1..10) {
    print "Hello, world\n";
}
[download]

Also, you may find some of the tutorials here useful if you're in a rush to see if you and LaTeX get along.

What I like in using noweb is the fact that I have just one file to edit. I can then extract the documentation (html, ps, pdf) and the several other files (e.g. perl-script, perl-module, sql-script, makefile). UC: I'm a real fan ;^)

Since you say you have two Lamport's books I suppose you don't have The LaTeX Companion. It explains in good detail a lot of useful LaTeX packages. I definitely reccommend it.

I recommend getting hold of the listings package.

It allows for short code snippets as well as long listings and file inclusions, source highlighting, supports a few dozen languages etc. etc. and even has a switch to display/not display POD in perl files.

Hmm... it might be a nice project to include that in pod2latex...
