Open FileMerge from command line

opendiff

If the command-line doesn't work, and you have no /Developer directory anymore, you probably need to: 
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

# Download the file manually from here https://launchpad.net/gcc-arm-embedded
# Note: `curl` command doesn't work
# I downloaded this one: "gcc-arm-none-eabi-4_7-2013q3-20130916-mac.tar.bz2"

# double click it to unzip it

# Make a place to install it to
mkdir /usr/local/gcc_arm

# Move the unzipped stuff there.
