 Simple single-file header-only CLI option parsing for C++.
-No subcommands or grouped commands.
-Only supports `-s value`/`--long-option value` style for options.
-Only supports `--long-flag` style for flags.
+* No std::regex

 ## Getting Started
 
 Download the latest [`argparse.hpp`](www.google.com) and include it in your project.
 
-## Features
-
-- [x] allow (default) / disallow (`Parser::no_unrecognize()`) unrecognized options and flags
-- [x] optional/required (`PosnlBase::required()`) positional arguments
-- [x] flags with `-s`, `--long-flag` formats
-- [x] options with `--long-opt val` format
-- [x] positional arguments
-- [x] `--` to stop parsing options and flags
-- [x] modify `argc`/`argv` (disable with `Parser::no_consume()`)
-- Option/Positional Argument Types
-  - [x] `int`
-  - [x] `size_t`
-  - [x] `float`
-  - [x] `double`
-  - [x] `std::string`
