## What it is
A Rust library that parses command line arguments by defining a struct, combining clap with a custom derive macro. It is now in maintenance mode since its features were integrated into clap v3.

## Use cases
- parse command line arguments in rust
- define cli options with structs
- generate help messages from doc comments
- build rust cli tools with typed arguments
- migrate from docopt-style parsing to derive-based cli

## When to choose
- maintaining an existing rust project already using structopt
- working on a rust codebase pinned to clap v2 that needs derive-based argument parsing

## When to avoid
- starting a new rust cli project - use clap v3/v4 derive instead
- needing features not present in structopt since no new features will be added

## Facets
- artifact type: library
- maturity: maintenance
- function: cli, parser, developer-tools
- domain: developer-tools, parsers
- platform: rust, cli, cross-platform
- tags: clap, derive-macro, argument-parsing, rust, command-line
