Simple Applicatoin & Library Example

Hi All.

Cool tool, hope to use it for all my projects.  I however am having 
trouble getting the following to work.

Basically I have a app that has a 'lib' directory and an 'app' 
directory.  The lib directory is built into a static lib and the app 
directory is built into an executable statically linked with the lib.

I have:
lib-tester
    /main.aap
    /lib
        /hello.h
        /hello.cpp
        /main.aap
        /libhello.a      (build from running with main.aap)
    /app
        /tester.cpp
        /main.aap

If I do the following it works:
$cd lib
$aap
$cd ../aap
$aap
$./tester

However I am not able to just run aap against the 'root' main.aap.  I get:
Aap: No target on the command line and no $TARGET, build rules or "all" 
target in a recipe

Also, if I do not manually run aap in the lib directory before running 
aap in the app directory I get then the compilation fails because the 
linker can't find -lhello.

I have checked the documentation as well as the mailling list and can 
not resolve the issues.  This would be nice example to add to the 
documentation once I figure it out as I believe this is a common 
scenario.  At least I do it that way. 8-)

So basically my questions is:
1) How do you 'force' a ':lib' target on an ':program' target.  I tried 
to ":include' the lib main.aap but no luck.
2) How can I simply have the root main.aap build all libs (in this case 
just one) and then build all the apps (again in this case just one).

I am happy to try out options and provide documentation writeup 
afterwords if that would be helpful.

Thanks.

Steve
