+ROOT - A data analysis framework.
+
+ROOT is a data analysis framework used mostly, but not limited to,
+high energy physics. It was written in C++ by the techs at CERN to
+explore the benefits of object oriented programming in physics data 
+analysis. It consists of libraries, CINT or cling interpreter for
+C/C++, plotting interface and powerful parellel processing support.
+It is the preferred choice in many laboratories.
+
+It comes with A LOT of different options for compilation. And it
+seems impossible to stress all of them in this one script. Therefore
+the potential user is strongly advised to check the configure
+script.
+
+The script was written to suit basic offline data analysis with
+possible GSL and FFTW support with full documentation and tutorials.
+It should be more than enough for normal user.
+
+It has 2 optional dependencies: GSL (accessible from SlackBuilds)
+and fftw (part of the official Slackware packages).
+
+Script has also mathmore support, for which one needs to GSL.
+
+Compilation takes quite a while.
+
+To steer the SlackBuild script, run it with these variables:
+
+GSL=yes(no) MATHMORE=yes(no) FFTW=yes(no) QT=yes(no) ./root.SlackBuild
+
+where the values in brackets are the default values that will
+be used unless specified otherwise.
+
+Note that by default this script will install things in /usr/ROOT:
+it will add /usr/ROOT/lib$LIBDIRSUFFIX to /etc/ld.so.conf and a
+profile.d script to set the correct PATHs.
