At present, Boodler 2.0 is available only as source code. See the installation docs for what to do with it.
Boodler's sounds and soundscapes are now collected in the Boodler package library. See the documentation on using Boodler.
Some scripts that make Boodler better, but which are not yet part of the source distribution:
/etc/bash_completion.d.

The original version of Boodler, and all its accoutrements, are available from the Boodler 1 page.
