# clap

Command-line argument parsing with a fluent builder. Build an `App`, attach `Arg`s, and read a typed `ArgMatches` back.

```cplus
import "clap/clap" as clap;

let app = clap::App::new("mytool")
    .version("0.1.0")
    .arg(clap::Arg::new("verbose").short("v").long("verbose").flag());
let m = app.get_matches_from(argv);
if m.is_present("verbose") { /* ... */ }
```

Long options accept both `--name value` and `--name=value`; short flags accept the combined `-abc` form. `get_matches_from(args: Vec[str])` is the cross-platform entry point. `ArgMatches` exposes typed accessors: `is_present(name)`, `value_of(name) -> Option[str]`, `positional_count()`, and `positional_at(i)`.
