A header-only options parser intended to specifically address limitations of other common parsers in an easy-to-use syntax while taking advantage of language features available in c++11.
Current support is for *nix although there should be no reason it cannot support Windows as well. If there are interested folks in this capability, please contact me.
The library provides large amounts of standard and custom functionality to include strict POSIX or GNU-style argument syntax, constraints on the number of argument or operands, option and operand mutual inclusion and exclusion, implied options and operands (i.e. if --foo implies --bar). Additionally, a low-level API is exposed that allows significant customization of option and operand handling while still integrating into the standard interface.
Take a look at the wiki for additional documentation on advantages, limitations, and sample code.
Licensing is permissive BSD 3-clause. If this bothers you and you would like to use it under a different licensing model, let me know. I generally don't care as long as someone doesn't claim they wrote something that they didn't.
