Please note that Gnus gets very angry if something else frobs its
files.  So it is best to tell procmail to deliver mail for the group
nnml:foo.bar into the file ~/spool/foo.bar.in, and then to set up
mail-sources like this:

(setq mail-sources '((directory :path "~/spool" :suffix ".in")))

Please note that the file is ~/spool/foo.bar.in (with a dot between
foo and bar) even if Gnus uses the directory ~/Mail/foo/bar (with a
slash between foo and bar) for the group.

The same setup also works for nnfolder and other backends, you do not
have to change the mail-sources setting, just
gnus-secondary-select-methods.

I define a function kai-gnus which does the Gnus-specific setup.  Then
the Gnus Emacs is started as "emacs -f kai-gnus".

The other Emacs is started as "emacs -f server-start".
