julia-basic is the name that appears in the emacs status line when it
can't find julia.  I verified it still appears with the latest git
version.

Regardless, why does C-x C-b after failing to find the program stick me
down on the status line with the with a query like
ESS (*julia:3*, julia-basic) starting data directory? ~/UCSF/HIVRace/
instead of showing a list of buffers?

It's possible the comment in ess-julia.el needs to be updated, since
that's where I got the idea for setting the julia location:
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

;;  customise inferior-julia-program-name to point to your julia-basic
;;  and start the inferior with M-x julia.
;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;

Since using inferior-julia-program-name seems to work, it must be at
least a fall-back option in the current code.

I forgot to mention one point earlier:
(setq inferior-julia-program-name "/usr/local/bin/julia")
precedes loading ESS in my .emacs.  I don't know if that's necessary,
but if it is that would be dicey for those using the packaged version on
Debian.  It loads all the packages before reading ~/.emacs.

Are there any plans for the ESS manual to include an ESS for julia
section, parallel to the other languages?
