Re: [Boost-build] [bbv2] newbie: how to get value of a feature inside a rule

This should go in the FAQs because I had to figure this out myself just  this week.  The toolset.flags rule sets your TOOLSET variable "on"  $(targets) for the actions block.  The undocumented magic method  to retrieve that value in a rule context is the following:
  
  local toolset = [ on $(targets) return $(TOOLSET) ] ;
  
  Voila!

rule but with no luck.
