Getting started with dev_appserver.py on a Mac
Thursday, April 10, 2008 by Dave Winer.
I want to work my way through the AppEngine tutorial on google.com. I've got a sub-folder set up in my Documents folder that contains the Helloworld app, per the instructions. But I get an error from dev_appserver.py that indicates (I think) that it's not finding the folder. I've tried every variation of changing directories and specifying paths, and keep getting the same error. 
Update #1: Kevin Marks figured out the problem. Textedit was adding an invisible .txt extension on the file. I wrote a script to remove the extension and got past that problem. Now I'm getting a syntax error on the Python file.
Update #2: It's Unix, the line-end char has to be \n.
Update #3: http://dwtestbed.appspot.com/ 
Update #4: Screen shot of the app dashboard.
