[boost] New Library Proposals

Hi, I'd like to solicit interest in the following brief proposals for inclusion in the Boost library. cla (Command-Line Arguments) - A generic C++ framework for parsing command-line arguments. The library design would be based on the popt (http://www.rpm.org/dark_corners/popt/) library. uom (Units Of Measure) - A generic C++ framework for arithmetic calculations and conversions between different units of measure. The library design would be based on The Units Of Measure Library (http://tuoml.sourceforge.net/). Questions and comments welcomed. Thanks, Eric.
