Functions
template<typename T >
OAttr< T >	oattr (std::string name, const T &value)
	Output manipulator for writing attributes.
template<typename T >
std::ostream &	operator<< (std::ostream &os, const OAttr< T > &oa)
	Output operator for attributes.
std::string	hashline (std::string s)
	Helper function to make sure that each line in the string s starts with a #-character and that the string ends with a new-line.

Detailed Description

The LHEF namespace contains some example classes for reading and writing Les Houches Event Files according to the proposal by Torbjörn Sjöstrand discussed at the MC4LHC workshop at CERN 2006.
