+dnl This tries to do the "right thing" to locate the boost include files.
+dnl If the user explicitly specified --with-boost-include-dir=<foo>
+dnl we believe them and use it.  Otherwise,
+dnl
+dnl We look for boost/shared_ptr.hpp in the "normal places".  That is,
+dnl wherever AC_CHECK_HEADER looks.  If the boost includes are in /usr/local/include
+dnl this step will find them.
+dnl
+dnl Otherwise, we check to see if the boost stuff was installed in a version-specific
+dnl directory under /usr/local/include.  These look like: /usr/local/include/boost-1_33_1
+dnl If there's more than one version installed, we select the
+dnl lexicographically greatest one.
+dnl
+dnl If none of these work, we bail.
