Using PTP for loading CHDK and CHDK uBASIC & Lua ScriptsEdit

One major hassle with developing code for CHDK - either with porting for a new camera, developing new functions or simply writing uBASIC & Lua scripts it the need to get that code onto your camera's SD card. Swapping the card between the camera and a card reader on your PC is time consuming and puts a lot wear and tear on your camera, SD card and PC card reader. Fortunately, once you have CHDK running on your PC you can use the chdkptp program (on Windows or Linux) to load your scripts and code over a USB cable
