 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.

 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
 =====================================
 
-You need to specify
-  --with-cint=$CINTSYSDIR
-...
+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!
