Boost C++ Libraries: Ticket #4144: boost::program_options::parse_enviornment lacks allow

Boost C++ Libraries: Ticket #4144: boost::program_options::parse_enviornment lacks allow_unregistered https://svn.boost.org/trac10/ticket/4144 allow_unregistered should be an option for the parse_environment parser. Given a suite of tools that share some but not all options, parse_environment forces all programs to register all possible options. Given a suite of tools progb and progc such that: progb --opta --optb progc --opta --optc are valid options to parse, using parse_environment(desc, "PREFIX_") will only work for PREFIX_OPTA. If PREFIX_OPTB or PREFIX_OPTC are set the other program will fail. en-us Boost C++ Libraries /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/4144 Trac 1.4.3
