That comment is out-of-date; as you see, CALLER_MODULE is
not being used.
The most reliable way to declare targets outside of Jamfiles is
project python ;
.project = [ project.current ] ;
rule whatever-rule-wants-to-declare-targets ( )
project.push-current $(.project) ;
... declare targets ...
This will always declare targets in the python project, even if you
have multiple "using python" and between those "using" some
other python is declared.
