Maybe if the rule generated by the type rule:

The first way applies when your target rule should just produce a target 
of specific type. In that case, a rule is already defined for you! When 
you define a new type, Boost.Build automatically defines a corresponding 
rule. The name of the rule is obtained from the name of the type, by 
downcasing all letters

as described here:

http://www.boost.org/boost-build2/doc/html/bbv2/extending/rules.html

were described, in terms of the Boost.Jam statements used in the
body or the rule, things would be clearer.  From an earlier
Volodya post:

http://article.gmane.org/gmane.comp.lib.boost.build/16245

I'm assuming this generated rule calls:

   targets.main-target-alternative

It would probably be helpful if the interface between
Boost.Build and Boost.Jam were defined in terms of how
something in Boost.Build were translated into something
in Boost.Jam.
