[ODE] ODE-0.6, OPCODE Compilation

[Tristan McMillan]

Hi

This maybe a simple newbie question but in the OPCODE README-ODE.txt the
following is said:

"If you want to use the TriList (triangle mesh) geometry class in ODE,
the OPCODE library must be compiled. To do so, simply uncomment the
OPCODE_DIRECTORY variable in ODE's user-settings file, and ODE's default
build system will compile OPCODE for you."

But what file name is the ODE's user-settings file.

Thanks very much,
Tristan
