Re: how to help? (wisent-java-default-setup)

Hi Jeff,

I think if JDEE instructions read mostly as:

;; do CEDET install
(load ...)
;; do JDEE install
(load ...)

Then you can put it anywhere in the JDEE startup code and it will 
override the CEDET autoload of the same style.

If there is some change needed in CEDET, let me know.
