I've been working on a Python version of the XSTOOLs software for a while now, but I finally got around to making it into a package. Distributing it as a ZIP file was becoming too much of a hassle.

Now all you have to do to install it is type:

You've probably read quite a bit of commentary about Curiosity's landing on Mars last night. Well, here's "Yet Another Mars Science Lab Blog Post".

First off, great job! NASA and JPL made an incredibly complicated job look easy. It took millions of man-hours of mind-numbing effort to get to that point. Now I'm excited to see what Curiosity digs up. It's a great achievement.
