documentation of the config-options?

Hi folks,

perhaps I'm stupid (I don't hope so ;-)) but is there any
documentation of the config-options.
I read, that the author doesn't give any support and I should
dig into the code to find out how it works but ...
I just want to use mathopd not to develop it ;-)!

So I am hoping for one of the users which could provide some
documentation.

Thanks a lot

Thomas
