Optimization function that deals with equality and inequality nonlinear
constraints.					

Ipopt-Scilab interface provides an optimization function that uses Ipopt
optimizer. It can solve large-scale problems with equality and inequality
nonlinear constraints. This Scilab-Ipopt interface was based on the Matlab Mex
Interface developed by
Claas Michalik and Steinar Hauan. This version only works on linux, scons and
Scilab >=4.0. Tested with gcc 4.0.3. The interface was not fully tested and is
in its beta version. Contributions are welcome!
