yes, one thing worth looking into is Tool Help.

as well as:

it is up to the reader to figure out how to use all this (sadly, nowhere

apparently it is possible to make all this work, though granted I was not
aware of all this when I wrote my stuff, so I had ended up using a much more
"manual" set of approaches when implementing my symbol lookup (manually
loading and processing the binary...).
