Hi Chris,
You can currently include +incdir+ options in .f files. You can also include .f files inside another .f file (as of 0.6.1.ea05) . One approach to this issue is to create an argument file for SVEditor. For example:
-f <files_file>

From your feature request, it sounds like you'd like to be able to specify include directories somewhere outside the .f file -- for example, in the SVEditor project properties dialog. Is this correct?
