There's a "g-wrap" system where you describe the bindings between C and
Scheme in Scheme form.  This is extensively used with GnuCash to attach
Scheme bindings to C functions and vice-versa to allow scripting in
Guile.  g-wrap also supports RScheme, which I *think* has something to
do with Rice?

<http://www.cs.cmu.edu/~chrislee/Software/g-wrap/> is the home of
g-wrap.

Note that a slick part of g-wrap is that it generates HTML documentation
as output; if you define some functions thus:
(new-function
 'gnc:get-num-accounts
 'int "xaccGetNumAccounts" '((AccountGroup* g))
 "Return the number of accounts, including subaccounts, in the account
group")

(new-function
 'gnc:group-get-num-accounts
 'int "xaccGroupGetNumAccounts" '((AccountGroup* g))
 "Return the number of accounts in the indicated group only
(children not counted).")

(new-function
 'gnc:group-get-account
 'Account* "xaccGroupGetAccount" '((AccountGroup* g) (int n))
 "Return account number n in account group g.")

g-wrap will generate a web page with the names of the functions and
arguments.
