-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. When using GCC3 as compiler please use at least CLN-1.1.1
-since some parts of GiNaC won't build with CLN-1.1.

-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
-This variable does not have to be exported for running the installed
-binary: since the actual program is started by a launcher that sets it.
-Enjoy!
-
-Here is an overview to gives you an idea if you can expect GiNaC-cint
-to compile, install and work properly:
-
- Cint version | how it works
---------------+----------------------------------------------------------
- < 5.14.39 | `VERBOTEN' by license (please bite your favorite lawyer)
- < 5.14.62 | since GiNaC version 0.7, these do not compile any more
- 5.14.64-86 | compiles fine, works well with GCC 2.95.x. GCC3 no go.
+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 GiNaC interactive shell, ginsh, makes use of GNU readline to provide
+command line editing and history. If readline library and/or headers are
+missing on your system, the configure script will issue a warning. In this
+case you have two options:
+
+1) (the easiest) If you don't intend to use ginsh (i.e. if you need GiNaC
+library to compile some piece of software), ignore it. ginsh builds just
+fine without readline (obviously, it won't support the command line history
+and editing).
+
+2) Install GNU readline and run the configure script once again. Depending on
+what your system/distribution is, you will have to install a package called
+libreadline and libreadline-dev (or readline-devel). 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.
+
+Problems with missing standard header files
+-------------------------------------------
+
+Building GiNaC requires many standard header files. If you get a configure
+error complaining about such missing files your compiler and library are
+probably not up to date enough and it's no worth continuing.
