Download this script which will allow you to automatically get the latest version of boxenv at any time from the CVS server. Or, you could simply go download the latest stable version.
Using the resource listed above, you can download the documentation. But if you want to read it online, we have an Online Copy of the documentation just for you.
This new boxenv web-site is still in it's early stages of construction. Until it's done, you can look for all the information you need (except the above script) at the old site.
