[NTG-context] Why is my module not automatically included?

Hello list I tried to compile the CV from [1] with context. But it does not recognize the module m.resume.tex in the same directory, I had to use the flag --usemodule=m-resume.tex. Why is that so and is there a way to let context detect my module automatically? Thanks for any hints. Cheers Reza [1] http://wiki.contextgarden.net/Curriculum_Vitae
