How do I download/install Pytave?

First, you'll need to install the bzr software. Second, you'll need to check pytave out from the code branch on launchpad.net (with the command 'bzr checkout lp:pytave'). Third, read and carefully follow the INSTALL file with detailed instructions on building and installing.

This is straightforward to do on POSIX systems like GNU/Linux. If you learn to do these steps, you'll be able to install almost any program delivered in source code form.
