[Open Babel] How can I convert .mkl to any fomat that can be read in Molekel?

[李乐生 <len...@gm...>]

Recently I am working with deMon, its manual says with the keyword
Visualization and the option MOLEKEL, the output file .mkl can be read in
Molekel, but what happened to me is opposition.
So I sincerely hope someone could do me a favor to solve this problem.
Thank you all.
