Sam,

What Jason meant is that in his example he used .SUBDIRS with a body
just to make it concise. You can use a .SUBDIRS without a body and put
Jason's code into the OMakefile files in the subdirectories.

Alternatively, you can keep Jason's format of a .SUBDIRS with a body and
use an explicit "include OMakefile" inside each .SUBDIRS body (this form
is useful if you include several directories with a single .SUBDIRS -
you use the .SUBDIRS body for the code that's common for each directory
and then put the custom code into an OMakefile).
