Could this be made easier?

1. Download tahoe-dogfood.zip.
2. Double-click on tahoe-dogfood.zip to unzip it.
3. Browse to the newly created folder, tahoe-dogfood.
4. Double-click on tahoe-grid-volunteer.py.
5. Drag and drop files to/from the file browser window that appeared
when you double-clicked on tahoe-grid-volunteer.py.

If there were a Python equivalent to JAR files, steps 2, 3, and 4
could be unified. "PySHAR" or something. That would be handy...

1. Download tahoe-dogfood.py.
2. Double-click on tahoe-dogfood.py.
5. Drag and drop files to/from the file browser window that appeared
when you double-clicked on tahoe-dogfood.py.

"Okay, Gawain, Ector, and Boors. That's five." -- "Three, sir!" -- "Right!!"
