[eclipse-clp-users] clpqr

1) Anyone here can advise on how to download, install and use the
third party library clpqr? (I couldn't get into the original website
of the software.) 2) Does clpqr have thhe capacity to simplify the constraints?
3) If clpqr is not avail now, which library is the closest to CLP(R) (real domain)?
I am using this library for teaching purpose. Thank you.
