Is there a converter for Monsters from the old Adventure Tools?

[valeros]

Is there a tool to convert the ".monster" files from the old Adventure Tools into FG?

I have a bunch of monsters from "Revenge of the Giants" that I previously converted to the new standards for damage, defenses, etc. using the old Adventure Tools. I thought I previously saw a thread about a tool to convert the ".monster" files into FG but I cannot find it (if it exists.)

Thanks
