* kernel/bootstrap.jam: Allow option handler modules to indicate that regular build process should be skipped. * options/help.jam: Return 'true', don't EXIT. Existing prevents header scanning, which is the mechanism that makes 'doc' module work. * new/doc.jam: Import header scanning rule into global module. (split-symbol): Handle the case where the are two modules with the same name (e.g. V1 stlport.jam and V2 stlport.jam). [SVN r18663]
