+The time the "make" step takes depends heavily on optimization levels. Large
+amounts of memory (>128MB) will be required by the compiler, also depending
+on optimization. To give you a rough idea of what you have to expect the
+following table may be helpful. It was measured on an Athlon/800MHz with
+"enough" memory:
+
+step | GCC optimization | comment
+ | -O1 | -O2 |
+--------------+---------+---------+----------------------------------------
+make | ~6m | ~8m | shared and static library
+make check | ~8m | ~12m | largely due to compilation
+
+
+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:
+<http://www.ginac.de/pipermail/ginac-list/2007-November/001263.html>
+
+Finally, run
+
+ $ autoreconf -i
+
+to generate the `configure' script, and proceed in a standard way, i.e.
+
+ $ ./configure
+ $ make
+ [become root if necessary]
+ # make install
+
+COMMON PROBLEMS
+===============
+
+Problems with CLN
+-----------------
+
+You should use at least CLN-1.1, since during the development of GiNaC
+various bugs have been discovered and fixed in earlier versions. Please
+install CLN properly on your system before continuing with GiNaC.
+
+Problems building ginsh
+-----------------------
+
+The most common reason why this doesn't succeed is the absence of GNU
+libreadline and/or the corresponding header files. Depending on what your
+system/distribution is, you will have to install a package called
+libreadline and maybe libreadline-dev. If your system's vendor doesn't
+supply such packages, go to <ftp://ftp.gnu.org/gnu/readline/> and compile
+it yourself. Note that non-GNU versions of libreadline (in particular
+one shipped with Mac OS X) are not supported at the moment.
