[ESS] Buffer *ESS*?

[Leon]

Hi all,

When I have "(require 'ess-site)" in my ~/.emacs, I get an extra
buffer named "*ESS*" even though I have not started any ESS
session. The buffer has these lines:
,---------------[ buffer: *ESS* ]
| [ess-site.el]: ess-customize-alist=nil 
| [ess-site.el _2_]: ess-customize-alist=nil 
| (S): ess-s-versions-create making M-x defuns for (R):
| ess-r-versions-create making M-x defuns for
------------------------------------------------------------------------

I don't know what's the use of this buffer. Shouldn't it be present when
user has actually started a session?

Cheers,
