Detailed Description

Class to write a C binary (cf. below) file of a given name and to fill it with information used as input to pede. Use its member functions mille(...), special(...), kill() and end() as you would use the fortran MILLE and its entry points MILLSP, KILLE and ENDLE.

For debugging purposes constructor flags enable switching to text output and/or to write also derivatives and lables which are ==0. But note that pede will not be able to read text output and has not been tested with derivatives/labels ==0.
