[Boost-build] custom generator can't get depends rule to work

Hi,

I'm still struggling with an antlr generator for boost.build.

I have 2 antlr files: Base.gl and Simple.gl.

 From Base.gl antlr builds:
BaseLexer.cpp
BaseLexer.hpp
BaseTokenTypes.hpp
BaseTokenTypes.txt

and from Simple.gl antlr builds:
SimpleLexer.cpp
SimpleLexer.hpp
SimpleTokenTypes.hpp
SimpleTokenTypes.txt

I have a custom generator that I think tells boost.build all it needs to 
know to build these files. Unfortunately I can't get dependencies to 
work. Simple.gl essentially includes BaseTokenTypes.txt and I can't work 
out how to use the INCLUDES rule to get boost.build to create 
BaseTokenTypes.txt when required.

I've tried adding the simple:
INCLUDES Simple.gl : BaseTokenTypes.txt ;
in the generator and other permutations but I can't see what I'm 
missing. The documentation suggests that the INCLUDES rule should accept 
the filenames. Do I need to set up the LOCATE variable on the built 
targets, in particular BaseTokenTypes.txt? I haven't managed to get this 
to work either :(

I attach the jam code.

Thanks,
John.
