+GiNaC requires the CLN library by Bruno Haible, available from either
+one of the following FTP-sites:
+  * <ftp://ftp.santafe.edu/pub/gnu/>,
+  * <ftp://ftp.ilog.fr/pub/Users/haible/gnu/> or
+  * <ftp://ftpthep.physik.uni-mainz.de/pub/gnu/>.
+You will also need a decent ANSI-compliant C++-compiler.  We use
+`post-EGCS' GCC, i.e GCC >= 2.95 for development so if you have a
+different 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.
+
+Optionally, GiNaC may work together with Masaharu Goto's free C++
+interpreter Cint.  You may obtain it from
+  * <ftp://root.cern.ch/root/>.
+Install it by following the instructions included in Cint's
+distribution before trying to compile GiNaC-cint.  (See section
+`Working with the Cint C++ interpreter' below.)

+COMMON PROBLEMS

 Problems with CLN
-=================

 You should use at least CLN V1.0.3, since during the development of
 GiNaC various bugs have been discovered and fixed in earlier versions.
@@ -60,3 +77,37 @@ To protect you, the "configure" script checks for a feature that was
 added in V1.0.3 so it won't continue with earlier versions anyhow.
 Please install CLN properly on your system before continuing with
 GiNaC.
+
+Problems with building ginsh
+----------------------------
+
+The most common reason why this doesn't succeed is the absence of
+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.
+
+
+Working with the Cint C++ interpreter
+=====================================
+
+Please see <http://root.cern.ch/root/Cint.html> to learn about Cint
+and install it prior to installing ginaccint.  For the interpreter-
+compiler `makecint' to work properly, the Makefiles need to know where
+Cint has its system directory.  This is usually done by exporting
+$CINTSYSDIR to point to the proper place.  With GiNaC you may either
+try to export that variable and type
+ $ ./configure --with-cint
+or specify it directly on the command line by saying
+ $ ./configure --with-cint=/my/path/to/cintsysdir
+Enjoy!
+
+Here is an overview to gives you an idea if you can expect GiNaCcint 
+to compile, install and work properly:
