-You will also need a decent ANSI-compliant C++-compiler. We recommend
-the C++ compiler from the GNU compiler collection, GCC >= 3.0. If you
-have a different or older compiler you are on your own. Note that you
-may have to use the same compiler you compiled CLN with because of
-differing name-mangling schemes.

+To build the GiNaC tutorial and reference manual the doxygen utility
+(it can be downloaded from http://www.stack.nl/~dimitri/doxygen) and

+Known to work with:
+ - Linux on x86, Alpha and Sparc using GCC 3.x and 4.0.
+
+Known not to work with:
+ - GCC 2.96 or earlier because proper exception and standard library support
+ is missing there.
+
+If you install from CVS, you also need GNU autoconf (>=2.59) and
+automake (>=1.7) to be installed.
