 The purpose of \fBhybrj_\fP is to find a zero of a system of
 \fIn\fP nonlinear functions in \fIn\fP variables by a modification
 of the Powell hybrid method. The user must provide a
-subroutine which calculates the functions. The Jacobian is
-then calculated by a forward-difference approximation.

 \fBhybrj1_\fP serves the same function but has a simplified calling
 sequence.
