Thank you.

Yes, I have one. :)
This example works fine if we already have a source of type GCI and no
conversion from another type is required. Imagine that we have a
source of type X and two generators: the first performs conversion
from X to GCI and the second -- from GCI to CPP. I have incomplete
notion how bjam composes a chain of spawned generators but I'm sure
that the generator from GCI to CPP will always fail because it has no
idea about sources of type X.
I have solved this problem by using the rule
generator.convert-to-consumable-types but I thought the easiest way to
write a custom generator is to override the rule
generator.generated-targets only. Am I on the right road? :)

WBR,
Denis.
