Installing Doxygen on Mac OS X
Just a quick note – I was guided toward doxygen, which is a tool that does source code documentation. It has a DMG installer, that includes an executable to run doxygen with a wizard.
But since my purpose was to run doxygen in an Ant build script, I needed to install the command line version.
I simply looked inside the application, and was able to see that the executable was in /Applications/Doxygen.app/Contents/Resources/
Adding a symbolic link to /usr/local/bin (which is in my PATH) did the trick:
sudo ln -s /Applications/Doxygen.app/Contents/Resources/doxygen /usr/local/bin
