Examples of embedding guile

[Derry Bryson <dbbuile at ta1 dot reno-onramp dot com>]

Hi,

I am new to this list and perhaps am asking a FAQ.  I appologize,
in advance, if so.  I browsed through several months of archived
messages but didn't see anything relevant.

I am beginning a program which will be a spreadsheet type program
and I hope to use Guile as the formula/macro language (i.e. where
the value of each cell would be a guile(lisp) expression).  

The original idea (brain fart) was to use lisp as a "formula language"
in a spreadsheet.  I was working with MS Excell and thought "wow, what
if instead of these stupid formula's, I could just use a lisp
expression?"  Then, of course, I began imagining what would be
possible.  Anyway, while considering if I wanted to implement my own
lisp interpreter (again), I remembered that Guile was a Scheme
interpreter and intended to be embedded;  this would be perfect!

So anyway, here I am.  I have downloaded and compiled Guile, but didn't
find much in the way of docs or examples.  What I am hoping for is some
simple example code that demonstrates embedding and utilizing Guile. 
Does anyone have any pointers?

Thanks,

Derry Bryson
