My bjam log says:

I noticed docbook.jam has a different comment style than other .jam files:

type DOCBOOK : docbook : XML ;

It seems that "Copyright" is being interpreted as a rule, and it's not 
parsed as a command. Should I update something in my runners? I tried to 
clean all build temporaries but it does not seem to solve anything.

Best,
