PSU Lush 1.1

Hi all,

I have been working on a derivative of Lush this year, which
we call "PSU Lush" here at Portland State University. I plan
to make an announcement on lush-users soon (but before I do
so I need to get the gnuplot interface right, which still has
some stability problems at the moment).

Download the (pre-)release from here:
ftp://ftp.cs.pdx.edu/pub/psu-lush/

PSU Lush is set up so that you may install it in parallel
to an existing Lush installation. The only file that's shared
is the file ~/.lush/lushrc.lsh. If you have stuff in there,
you probably need to do

(when (= version "lush")
   ;; lush stuff
)

(when (= version "psu-lush")

   ;; psu lush stuff
)

because I made a number of backward incompatible changes.
My focus was on improving the array API. Only a few of Lush's
idx- functions discussed in Chapter 4 of the manual have
survived the overhaul (though I didn't get to the load and
save functions).

I appreciate any comments.

Thanks,
Ralf
