 This takes a while, but only has to be done once. If the defaults in the build do not work for you, and you need to set specific make parameters, you can save them in `Make.user`. The build will automatically check for the existence of `Make.user` and use it if it exists.

 In the terminal, Julia makes great use of both control-key and meta-key bindings. To make the meta-key bindings more accessible, many terminal emulator programs (e.g., `Terminal`, `iTerm`, `xterm`, etc.) allow you to use the alt or option key as meta.
