That doesn't mean that Boost.Build handles everything beginning with --xxx.
Any Jam code can access ARGV to handle extra options. Boost.Build
just ignores any options that it doesn't recognize.

Sandbox boost-build.jam has [ MATCH --boost=(.*) : $(ARGV) ].
Inside a module, you would need to use [ modules.peek : ARGV ].
