C++ argument parser library
This project builds and defines the build2 package for args, which is a simple, small, flexible, single-header C++11 argument parsing library.

Usage
Make sure to add the stable section of the cppget.org
repository to your project's repositories.manifest
to be able to fetch this package.

# trust: ...
If the stable section of cppget.org
is not an option then add this Git repository itself instead as a prerequisite.

Changes
* 6.0.0
Change Reader to functor type, breaking change.
Change Reader functor to allow any return type, but specifically need bool-testable return for NOEXCEPT use.
Change List and Map templates into template templates to enforce proper type use and to clean up user template invocations (i.e. `args::ValueFlagList<std::string, std::unordered_set<std::string>>` becomes `args::ValueFlagList<std::string, std::unordered_set>`, also breaking change.
* 5.0.0
Implemented proper subparsers.
Added better C++11 style.
Improved documentation.
* 4.0.0
Changed all wording:
ArgFlag -> ValueFlag
Counter -> CounterFlag
PosArg -> Positional
Argument now solely refers to command line arguments.
Value refers to the argument that flags or positionals can take and store.
Positional is a positional option, which contains a value.
Option refers to flags and positionals, which can contain values.
