[ArbolOne <arbolone gmail com>]

Hi kids!
I just need a little bit of help to find my bearing when using giomm. If 
some body would be so kind as to show me how this method would be change 
from std to giomm.

TKNX!!

const char* jme::strtools::toStr( const int x ) {
    std::stringstream num;
    num << x;
    tmp = num.str();
    return tmp.c_str();
}
