+curve fitting problems for Python.  It builds on and extends many of the
+optimization methods of @code{scipy.optimize}.  Initially inspired by (and
+named for) extending the Levenberg-Marquardt method from
+@code{scipy.optimize.leastsq}, lmfit now provides a number of useful
+enhancements to optimization and data fitting problems.")
