Re: [Boost-build] Broken? lib bar : : <file>...

Hi Vladimir,
  
  A lot of the jam/bb2 underpinnings is still just magic to me so please bear with me.  With
  
  lib foo : : <name>foo <file>/somewhere/foo ;
  
  my naive expectation is for the system to understand that  /somewhere/foo is a prebuilt library file ( but which subtype of LIB is  not clear because of no suffix - is that the rub?). Could the lib rule  be enhanced to understand something like:?
  
  lib foo : <name>foo <file>/somewhere/foo <type>SHARED_LIB ;
  
  Probably a dumb question but fools rush in.  Thanks for your generous patience.

And, what will Boost.Build do with such file? If it has no idea what's the 
type of the file, it has no idea if it can be linked into an executable.
Well, I can change generators code so that targets with unknown type are 
silently consumed and passed on to the tool (like linker), but that seems 
very fragile.
