 #
 # DESCRIPTION
 #
 #   Test for the Boost C++ libraries of a particular version (or newer)
 #
-#   If no path to the installed boost library is given the macro
-#   searchs under /usr, /usr/local, and /opt, and evaluates the
-#   $BOOST_ROOT environment variable. Further documentation is
-#   available at <http://randspringer.de/boost/index.html>.
