I use the trunk on Mac. I actually downloaded MacHG, which is a GUI for
Mercurial, then did a pull from the web2py repository on to a folder on my
Mac. The way you get web2py from trunk is pretty much the same across all
platforms. If you want to update your executable to the trunk version, you
might be able to right click on the app, Show Package Contents, find where
the web2py folder is, and write over it with the trunk version. But BACKUP
before you try this, because I've never done it before, and have no idea if
it will work.
