-Installation
+GiNaC requires the CLN library by Bruno Haible, available at 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 C++
+interpreter cint (which requires that you register for commercial
+use).  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.)

-Problems with CLN
-=================
+COMMON PROBLEMS
+===============

 
 

-You should use at least CLN V1.0.2, since all earlier ones are
-somewhat buggy.  Even V1.0.1 has a few problems and GiNaC will not
-support older versions.  Please install it properly on your system
-before continuing with GiNaC.
+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.
+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.  After that it should work fine.  
+
+If you want to build a completely static ginsh and your compiler still
+complains about unresolved objects try linking with libncurses, too.
+
+
+Working with the Cint C++ interpreter
+=====================================
+
+The interface to the Cint C++ interpreter is currently in an alpha
+state.  Please see <http://root.cern.ch/root/Cint.html> to learn about
+Cint and install it before installing ginaccint.  For the tool
+makecint to work properly it must 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 on the command line saying
+ $ ./configure --with-cint=/my/path/to/cintsysdir
+Good luck!
