-
-DESCRIPTION
-        These functions compute a projection of <[z]> onto the Riemann 
-        sphere: <[z]> projects to <[z]> except that all complex infinities 
-        (even those with one infinite part and one NaN part) project 
-        to positive infinity on the real axis. If <[z]> has an infinite part,
-        then <<cproj>>(<[z]>) is equivalent to
-
-                 INFINITY + I * copysign(0.0, cimag(z))
-
-        <<cprojf>> is identical to <<cproj>>, except that it performs
-        its calculations on <<floats complex>>.
-
-RETURNS
-        The cproj functions return the value of the projection onto 
-        the Riemann sphere.
-
-PORTABILITY
-        <<cproj>> and <<cprojf>> are ISO C99
