I'll second the enthusiasm for {e,c}tags! At my previous job, my duties
were maintaining and adding functionality to a customer's web site,
which was written in Perl. This particular Perl was OO Perl, but it was
horribly complex. One of the first things I did to get more familiar
with Perl and with the codebase when I was initially dispatched to the
client's site was to write a (reasonably generic) documentation
auto-generator for a hierarchy of Perl modules
(http://www.billjonas.com/code/ for a description,
http://www.billjonas.com/code/perldoc.tar.gz for the tarball if you're
interested). I found myself referring to the output of lineage (my
program) quite often as I tried to figure out exactly what steps were
being taken by the application. Finally, one day I said, "To hell with
this, I'm going to learn how to use ctags." Best thing I ever did! Now
I was just two keystrokes away from the definition of a function and two
to go back to exactly where I was, line and column.

I used Exuberant Ctags, which is (or was, at least in 5.x) distributed
with Vim. Vim looks for a file called "tags" in the current directory
when you try to invoke a tag function. If you want to jump to the
definition of a function, position the cursor over the name of the
function (some vi clones or Vi itself might require you to have the
cursor at the beginning of the word) and hit Ctrl-]. To go back to
where you were, hit Ctrl-T. (Yes, Ctrl-] conflicts with the telnet
escape character, but you should be using ssh anyway. <g>) ":help tags"
for more information. The sixth edition of the O'Reilly vi book has a
section on the more popular vi clones (vim, elvis, nvi, and vile) and it
covers their methods for tags operations.
I've gotta say, it's almost amazing to hit Ctrl-] and be taken to the
function definition in a totally different file.

Stone knives and bearskins, indeed. <g>
