It requires Python, which I don’t have installed on my Windows machine but I did have on my Mac. It installed fine with the standard Python on the Mac and after some confusion about my user account (I regularly log into Google with 3 different accounts) I was able to get it working and it’s pretty slick.
I downloaded Python and installed it on my Windows 7 workstation to see if I could get it working. Clearly I was missing a step somewhere because I couldn’t quite get it to run, but it appears to be that I’m missing some Python libraries that are installed on my Mac. I didn’t spend much time troubleshooting it because I will only be using it from my Mac, anyway.
What intrigues me most about it is the gdata API libraries for Python that it uses which I didn’t know existed. Now that I know about them, I can think of a number of interesting uses. There’s a lot more in the libraries than is exposed through the command line tool. Some powerful Google services that I didn’t even know existed. I’m going to curl up with a hot cuppa and read though them and get some fun ideas.
