+To install from CVS
+===================
+
+First, download the code:
+
+ $ cvs -d :pserver:anoncvs@cvs.ginac.de:/home/cvs/GiNaC login
+ [enter "anoncvs" as the password]
+ $ cvs -d :pserver:anoncvs@cvs.ginac.de:/home/cvs/GiNaC co GiNaC
+ $ cd GiNaC
+
+Secondly, make sure all required software is installed. This is *really*
+important step. If some package is missing, the `configure' script might
+be misgenerated, see e.g. this discussion:
