So here comes my first Textmate Bundle, thanks to the elegant work of Arduino team to make it easier to upload program from command line:

Arduino.tmbundle

Once installed, only one shortcut is available to make and upload your program on the Arduino board: Command-Shift-A

You can clone/fork the project from Github too, make your own repository and I’ll be glad to add your patch to the current simple bundle.
And come back during the week, you’ll surely see some update during the intensive RepRap hack session!
