Is there a program to convert OpenGL 2.0 to OpenGL-ES 2.0?

I have a 3D game library that uses OpenGL 2.0 for PC and I need to convert it to OpenGL-ES 2.0 to compile it for Android. Because the library is huge, it can’t be done by hand, so I was wondering if there is some kind of software to auto convert desktop OpenGL to OpenGL-ES source code, some wrapper, or maybe some layer running on Android that converts desktop OpenGL to ES on runtime? Perhaps there is a tool that auto converts desktop OpenGL to a cross platform 3D rendering library ?
