I've looked at the build system (i.e, Jam files) and noticed that most of time, the directories (include directories, link directories) are specified in absolute format - $(BOOST_ROOT)/whatever. However, not all of them are absolute. Some are relative - ../../../whatever. Other parts of the Boost tree, such as the html files, contain relative paths.
Actually all the paths are relative. $(BOOST_ROOT) expands to a relative path like ../../.. that is adjusted to a new appropriate value in each Jamfile.
Why is this so? What purpose does it serve, if I may ask. Why not just put the relative path in the files? Will this be useful for other projects? Thanks again.
