(bundle/install path &keys config )
Install a bundle from the local filesystem. The name of the bundle
is the value mapped to :name in either `config` or the info file.
There are 5 hooks called during installation (postdeps , clean ,
build , install and check ). A user can register a hook by defining a
function with the same name in the bundle script.
