The library is an autotools package, and is installed using the usual 
paradigm of configure; make; make install.

Along with the usual autotools options, the library's configure script offers the following options:
%

* --with-lhapdf-path=path_to_lhapdf_installation 

 Sets the location of the \textsc{lhapdf} installation. This option is needed only if the helper program lhapdf-config is not in the executable search path. 

* --with-root-path=path_to_ROOT_installation

 Sets the location of the root installation. This option is needed only if the helper program root-config is not in the executable search path. 

* --enable-pythoninterface

 Compiles the python interface

To install the library, unpack the ntuplereader-X.Y.Z.tar.gz file,
{{{
tar -xzf ntuplesreader-X.Y.Z.tar.gz
}}}
Configure, with options as needed,
{{{
cd ntuplesreader-X.Y.Z
./configure OPTIONS
}}}
and then compile and install,
{{{
make
make install
}}}
To install in a different location than the standard one, use the --prefix option to the configure script.
