+%description
+CMPFIT uses the Levenberg-Marquardt technique to solve the least-squares 
+problem. In its typical use, CMPFIT will be used to fit a user-supplied 
+function (the "model") to user-supplied data points (the "data") by adjusting 
+a set of parameters. CMPFIT is based upon MINPACK-1 (LMDIF.F) by More' and 
+collaborators.
