Aros/Developer/Docs/Libraries/TTEngine

Introduction
I assume that the includes used for contrib programs are the ones in:

AROS/bin/linux-i386/gen/include/proto

I would have expected them to use (assuming its a hosted build your doing..) -:

AROS/bin/linux-i386/AROS/Development/include/proto


 * 1) include   

This is for ttengine.library which is ported to AROS. For more info on the lib. Not in Contrib, because a (linklib) version of freetype isn't built. see AROS/workbench/libs/freetype.
