Agreed.

I put it in project-root.jam. Actually, that makes more sense since file 
extensions usually are project dependent. BTW, I think that creating a file 
called $HOME/user-config.jam will be repelling for the average UNIX user. 
Something like "$HOME/.boost-build/user-config.jam" would be more natural.

Definitely, AFAICS it provides everything that is needed and is easy to use.
