Actually that option says: "show the command line but don't build
anything."  To show the command line you add "-d+2".  And you have to
add these options before any options that begin with no hyphens or
double hyphens.  This is really stupid; it causes no end of
confusion.  How many times have we heard these questions?  bjam should
just work like make by default and show the full command lines, with a
--quiet option for those of us who don't want to watch all that junk.
