<longdescription lang="en">
ROOT Object Oriented Technologies is an object oriented data
analysis framework written in C++ by the CERN. Widely used in
high energy physics, but also in other data analysis applications. It
contains the CINT C/C++ interpreter and many classes such as
statistics, serialization, optimization, linear algebra, graphics,
GUI toolkit, and a complete visualization framework.

<flag name="cern">
Build the HBOOK input/ouput functionality. HBOOK is a histogram
library. On ROOT versions previous to 5.20.00, it will depend
on <pkg>sci-physics/cernlib</pkg>. On versions above, it only need
a FORTRAN compiler.
</flag>
<flag name="clarens">
Buld the Clarens and PEAC plug-ins, to use in a GRID enabled
analysis. The Clarens Grid-Enabled Web Services Framework is an
open source portal for ubiquitous access to data and computational
resources provided by computing grids. PEAC is an interactive
distributed analysis framework that uses Clarens as a glue
protocol to advertise and communicate amongst SAM, Global Manager
(GM), Local Manager (LM), DCache, and PROOF services.
It doesn't need Clarens to build, however if you want to use it,
you will require to build Clarens and PEAC on your own, it is not
yet in the Gentoo Portage tree.
See http://clarens.sourceforge.net/ for Clarens
and http://physics.ucsd.edu/~schsu/project/peac.html for
PEAC.
</flag>
<flag name="geant4">
Build the <pkg>sci-physics/geant</pkg> (GEANT4) navigator.
</flag>
<flag name="math">
Build all math libraries plugins. It includes
the <pkg>sci-libs/gsl</pkg> bindings in MathMore, the GenVector
physical vectors package, the Minuit2 minimization library (same as
standalone <pkg>sci-libs/minuit</pkg>), the RooFit toolkit for
distribution modeling, and the Universal Non-Uniform RANdom number
generators (UNURAN) library.
</flag>
<flag name="pythia6">
Builds the interface to Pythia-6 (<pkg>sci-physics/pythia</pkg>)
high energy physics generation events library.
</flag>
<flag name="pythia8">
Builds the interface to Pythia-8 (<pkg>sci-physics/pythia</pkg>)
high energy physics generation events library.
</flag>
<flag name="reflex">
Builds the reflection database for the C++ interpretor.
</flag>
<flag name="xrootd">
Build the xrootd low latency file server. For more on the eXtended Request
Daemon (xrd) and associated software, please see
http://xrootd.slac.stanford.edu.
