What do you mean "call explicit"? 'your-install' is a function, which
is called just like in any other language. It's metatarget that can
be explicit. If you want to make a metatarget explicit, you call
the 'explicit' function passing the name of the metatarget to it.
For example:

        explicit install install-bin ;

Does this help?
