BUILD AND INSTALL
=================
Generic installation instructions are in the file INSTALL.

Before attempting to build Herwig++, you'll need to get ThePEG
installed.

Herwig++ uses some functions from the GNU scientific library GSL. The
gsl libraries and header files must be available on your system.
Usually they can be found in a package called libgsl-dev. 

------
ThePEG
------

Download ThePEG 1.8.0 or later from 
http://projects.hepforge.org/herwig/versions
 
Do not build this package inside the Herwig++ source directory!

$ tar xjvf ThePEG-*.tar.bz2
$ cd ThePEG*
$ ./configure --prefix=/path/where/ThePEG/should/be/installed
$ make
$ make check
$ make install

Optional configure switches include --enable-unitchecks for checking
dimensional correctness of physical expressions in the code, and
--with-LHAPDF for linking against the LHAPDF library. See './configure
--help' for more details.
