[Boost-build] defining build variants

Hello,

I'd like to define a build "variant" (for lack of a better term) that
allows me to set some properties differently while executing the same tasks.

Specifically, I'm running 'b2' in python/doc to regenerate (HTML)
documentation. I'd like to be able to define build parameters (xsl:param
in my case) differently via command-line options.

Is it possible to have `b2 something` and `b2 somethingelse` execute the
same tasks, but with different values of these parameters ?

Thanks,
                Stefan
