Macports basics

[Eric Gallager]

I personally do not really use the "leaves" functionality that much,
but if you decide that you do want to go that route, there is a
"port_cutleaves" port that you can install (with `sudo port install
port_cutleaves`) that can be helpful for dealing with leaves. It is a
relatively simple script that actually comes from the "contrib" folder
in the MacPorts repo:
https://trac.macports.org/browser/contrib/port_cutleaves/port_cutleaves.in
