About:
argparse is a header-only C++ library that provides a flexible and intuitive API for parsing command-line arguments, inspired by Python's argparse. It supports a wide range of features including subcommands, automatic help generation, and type-safe argument validation. Its modern C++ design simplifies the creation of complex CLI interfaces without external dependencies.

Key Features:

Header-only library, no build or installation required
Supports subcommands, nested arguments, and automatic help generation
Type-safe argument parsing with custom validators
Modern C++11/14/17/20 API with intuitive syntax

Use Cases:

Building robust command-line interfaces for C++ applications
Parsing complex arguments and flags for scientific computing tools
Creating CLI utilities with subcommand structures like git

Alternatives:

CLI11 – CLI11 is another popular C++11 library for command line parsing, often noted for its robust feature set and performance.
Boost.Program_options – A part of the Boost library, it provides extensive configuration capabilities but is heavier and requires linking against Boost.
