[Boost-users] question of program_options : validator function

From: Suresh T (suresh.t_at_[hidden])

hello boosters, 

An old boost library that i was using, provided a validator function (in 
the value_sematic.hpp file) that could be used for
creating user defined parsers and it was handy

The signature was something like :
void validator<T, char>::operator()       (any& v, const 
std::vector<std::string>& xs);

I had a working code that used it  and when i tried to recompile my old 
code with a new boost release it did not compile.
 I then realized that the validator function is no longer there. 
Can someone please let me know if this has been substituted by something 
else (what?) or what i would have to use now in such cases.

Thanks in advance.
