Hi folks,

	Calculus with Xlisp-Stat is a project developed at Ripon College,
Ripon, WI, USA, to aid calculus students. I call it "Ripon Good Math".
It has also many important advantages for anyone using xlispstat, however,
including more natural (infix) function definition, easy plots, postscript
files, hidden-surface generation, etc.

	A tutorial is included, accessed by typing (tutorial). Also I've
re-written the Tierney book stuff so that it can be run from the command
line using (book).

	The code is available, and tested for UNIX, the Mac and
Windoze. I've stolen a lot of good ideas from the usual contributors to 
the xlispstat discussion group, and thank them for their hard work.

	I'm not smart enough to use all the provides and requires, however,
so I just load everything in, save a new environment, and always run from
within that.

trying and be patient!

UNIX:

Step 1: compiling

	If you're a unix user, simply save the file calculus.tar.gz to the
xlispstat directory, then type

gunzip calculus.tar.gz
tar -xvf calculus.tar
make rgm

in the directory where you've unpacked all this stuff (rgm stands for ripon
good math). 

	After everything compiles xlispstat will generate a new workspace
(.wks) file. This file will be located in the calculus directory.

Step 2: running

	You should either replace your existing xlisp.wks file with this one
(after first backing it up!), or change your xlispstat command so that it loads
this one in, or simply leave it where it is and, when you want to run in
"calculus mode", issue the xlispstat command from the calculus directory.


----------------------------------------------------------------------
Mac users:

Step 1: Setting up

	Put this stuff directly below *default-path* (usually where your
xlisp-stat application sits). Use Macgzip and tar to unwrap the calculus.tar.gz
file (both freeware for the mac). You should now have a directory called calculus
there.

	You should copy the original xlisp.wks file to the directory in which
all these files live. 

Step 2: compiling - this takes awhile, but saves time every time you run.

	Now click on xlisp.wks. Once xlispstat is running, load the
re-make.lsp file, followed by the RPM.lsp file. These will then create a
newxlisp.wks file, which you can use whenever you want to run xlispstat with my
extensions (or you could replace the existing xlisp.wks file, after backing the
original up), so that xlispstat runs in "calculus mode" all the time.


----------------------------------------------------------------------
Windoze users:

	I put the calculus.tar.gz file in the xlispstat directory, and used the
gzip and tar programs (that I got off the net) to unwrap it. Since I conform to
the 8.3 DOS format, you shouldn't have any trouble (although some of the
example files do not conform - these will not affect your ability to compile
and run, however).

	Then simply load the re-make file (note: many functions may not
compile, due to memory problems, but this doesn't seem to bother xlispstat when
it runs).

	The re-make file ends by booting you out of xlispstat. Re-run
xlispstat, then load the file RPM.lsp. This should create a new workspace,
called newxlisp.wks. Either rename this to xlisp.wks and replace the original
(after saving the original somewhere!), or double click on it to get started.

----------------------------------------------------------------------

	Okay, there it is. Please send me your comments, and I'll treat them
with respect.
