+To build the manual in PDF, HTML, or PostScript formats, use one of
+
+$ make pdf
+$ make html
+$ make ps
+
+To compile and run CLN's test suite and check whether the library was
+compiled correctly you can use
+
+$ make check
+
+The "configure" script can be given a number of options to enable and
+disable various features. Most useful ones are:
+
+--prefix=DIR
+
+Install CLN into the directory DIR (default: /usr/local).
+
+--with-gmp
+
+Use GNU multiprecision library (default: yes, if available)
+
+--disable-static
+
+Don't build static version of CLN library. This option is useful if
+want to reduce the build time (and you don't need the static library).
+
+For a complete list, run:
+
+$ ./configure --help

+Installation from git.
+=====================
+
+1. Download the code.
+
+Initial download:
+
+$ git clone git://www.ginac.de/cln.git
+
+Later on you can update your copy with
+
+$ git pull
+
+2. Make sure all required software is installed. This is *really*
+important step. If some package is missing, the `configure' script might
+be misgenerated,
+
+3. Run
+
+$ autoreconf -iv
+
+to generate the `configure' script, and proceed in a standard way, i.e.
+
+$ ./configure
+$ make
+[become root if necessary]
+# make install
