I have been working on a script that allows users to easily install and use the Particle toolchain on OSX and Ubuntu based distros. It takes care of installing dependencies and can be used to quickly compile and flash code to devices using dfu-util. The script downloads and installs: dfu-util, nodejs, gcc-arm-embedded, particle-cli, and the Particle Firmware source code. The script can be found at https://github.com/nrobinson2000/po-util
