This is a little arexx script which finds filetype and 
processes the files in a user-defined way similar to the
wb-datatypes.

Usage: bigactor "File"
(As bigactor is an arexx script you should set the script-bit)

Preferences: 

The prefs are stored in
envarc:ba3.action

you can easily add a filetype which is declared for whatis.library

TYPE Guide
multiview %s

these two lines are needed for passing all Guide files to multiview.
Now you only have create a button for Opus or an Appicon with one of
the many Tools for those purpose :)

Now edit the prefs-file to use your personal tools ...
