The smiley is only partly a joke. While environment vars have problems, i.e. 
they are near as expressive as user-config.jam, and are outside our control, 
using the BOOST_BUILD_PATH has some advantanges.

For example, when I'll make Debian package for Boost.Build, it will likely set 
BOOST_BUILD_PATH during installation, and user will not be requried to create 
extra file.
