[Boost-users] Wondering if any more doc for Boost Progam Options

Just started using the Boost Program Options library. Great stuff! Thanks! Was wondering if there is any more documentation anywhere? For example, is there any documentation for the various methods that can be passed to .add_options(), like boost::program_options::value()? I just happened to figure out boost::program_options::bool_switch() by chance. (I also had to hack my way through an assert to figure out that the "short" option tag, such as -t in ("sometag,t", . could only be one character.) The tutorial was a great start but the detailed documentation just seems to link to the header files which are largely uncommented. Thanks, Charles
