New Revision: 38620
URL: http://svn.boost.org/trac/boost/changeset/38620

Log:
Added support for BOOST_USER_CONFIG environment variable. This variable is able to take the same rhs as --user-config= switch. The switch still overrides the variable when present. (This has been added to allow for the BOOST_BUILD_PATH to be restored to its original i.e. documented behaviour.)
