Apart from what others already have said, I think that there's support for 
"pluggable" options. Adding a "option-name".jam file into 
<bbv2-root>/options makes Boost.Build load and invoke the specific module, 
IIRC.

I'm not sure if it's "officially" supported though, and is probably only 
meant for options included in the stock Boost.Build distribution. Still, 
it's a possibility.
