It's actually supposed to work in most cases. But the testdit needs to 
be a part of the project and should actually have a phony target "test" 
(either declared there, or inherited via ".SIBDIRS").

% cat OMakefile
.PHONY: foo

foo: .PHONY/bar/xyz

.SUBDIRS: bar

.DEFAULT: foo
% cat bar/OMakefile
.PHONY: xyz

xyz:
     echo "This is xyz"
% omake
*** omake: reading OMakefiles
*** omake: finished reading OMakefiles (0.1 sec)
- build bar <xyz>
+ echo "This is xyz"
This is xyz
*** omake: done (0.2 sec, 0/0 scans, 1/1 rules, 0/37 digests)

But if I delete the SUBDIRS line, then running omake would not do 
anything (this is weird even to me, but this ".PHONY/..." syntax is 
still an experimental feature).
