How do I install Tomcat 5.5.x on a non-Windows computer?

I'm learning how to develop Servlets & JSPs for a job interview and I want to install Tomcat 5.5.x on my Mac. I see that there is a "Windows Service Installer" but I don't see an installer for "Mac OS X". Does this mean that I need to download the source and build it as some kind of Mac/Unix software?

Can somebody point me in the right direction to get Tomcat 5.5.x to work on a Mac?

OSX is Unix.
Download the tar.gz file.
Unzip it to the directory where you want to keep Tomcat.
Follow the instructions for a unix install.
Start the server by running the TOMCAT_INSTALL/bin/startup.sh file.

Conventially, Tomcat is installed on Mac OS X in /Library so that it acessible from the Finder.

Yes, be sure not to grab the .zip file!
