The library can be downloaded here: http://www.hepforge.org/archive/blackhat/ntuplereader-1.0.tar.gz 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.
