Detailed Description

template<class T>
class ecl::ValueArgHelper::ValueExtractor< T >

TClap class internally used for extracting value args.

This class is used to extract a value from an argument. It is used because we need a special implementation to deal with std::string and making a specialised function puts it in the T segment, thus generating link errors. Having a specialised class makes the symbols weak. This is not pretty but I don't know how to make it work any other way.
