Boost support: --help in top-level dir; installting libs

Hi,
some time ago Rene noted that

bjam --v2 --help

in Boost top-level dir does not produce install help. Instead, it prints 
various options related to Boost.Build online help.

What's the best way to address this:
[ ] Make --help here produce only install help
[ ] Make --help produce both install help and Boost.Build online help
[ ] Introduce new --help-install or --help-project option, and mention it
in --help output.

Rene also noted that it's no way to install a specific boost library by going 
to it's libs/whatever/build and running "bjam install".
What's the best way to address this:
[ ] Introduce new top-level rule 'declare-install-targets' that each library
Jamfile will call (pretty easy)
[ ] Make top-level Jamfile automatically inject necessary targets in library 
Jamfiles (harder to implement, might be easier for library developers)
[ ] Introduce some mechanism for "inheriting" targets, so that all library
Jamfiles will inherit the "install" target (Sounds pretty complicated)

Options?
