Now we can compile this package inside or outside the CGAL tree.

+There are two ways to compile: inside the CGAL tree or outside it. Clearly,
+it is easier to do it the second way, but compiling inside CGAL will give you
+all the advantages of the install script.
+
+To compile inside the tree, it is necessary to copy all the files to the CGAL
+root directory, and install it in the normal way, using the provided modified
+script install_cgal.
+
+To compile outside the tree, just go to the directory src/Gbrs and type
+"make outside". It will install the library in the CGAL lib directory.
+Note that there must be present the environment variables CGAL_MAKEFILE,
+RS_INCL, RS_LIB, MPFI_INCL and MPFI_LIB.
+
+Have fun,
