Hello --

I have a question on using existing source trees with GNAT (3.05, migrated 
to 3.09, and now  moving to 3.10).

We have inherited a tree of sources with some files shared between branches,
roughly as follows:

        +-- processor 1        spec1.1, spec1.2, body1.1, body1.2, ...
        |
        |
  TOP --+-- processor 2        spec2.1, spec2.2, body2.1 <- with 1.1, ...,
        |                                        body2.2 <- with 1.x, ...,
                                                 ...
         (etc)

I don't know yet whether the cross-branch "with"s include object modules,
or only data types. The original developers are using APEX to manage their
builds; I am unfamiliar with the requirements of APEX, other than noticing
of a file in TOP which lists, for a given sub-directory, a set of "Import"s
which I expect are the branches containing units required in building that
sub-directory's executable(s).

Is this as simple as it would be for 'C' with '-I', '-l' and '-L' directives?
How do I set up dependency checking?

Sorry for what may be a trivial question, and I would be happy to pursue GNAT
or other documentation if someone will provide a pointer.  Thanks.
