Hello I would like to submit some changes to boost i.e. I have implemented an extension to boost to support extra conversion chars like %B for printing bool's symbolically i.e. switching on boolalpha, and %b to print out a integer type in binary (base 2) and %b(base) to print out and integer in base "base" 2<= base <= 36 and the uppercase flag controlling whether or not we use 'A' to 'Z' or 'a' to 'z' for digits above 9 Also I have implemented a printf, fprintf etc that uses C++0x's vardic template parameters to type safely print, this uses boostformat as the format string anyway I would like to submit this stuff to boost for hopefully inclusion in the boost libraries how do I go about that I cannot find it on the web page -- In my life God comes first.... but Linux is pretty high after that :-D Grizzly(Francis Smit) http://www.google.com/profiles/grizzlysmit
