@ -45,7 +45,7 @@ Below are a few of the features which `clap` supports, full descriptions and usa
* **Specific Value Sets**: Positional or Option Arguments can optionally define a specific set of allowed values (i.e. imagine a `--mode` option which may *only* have one of two values `fast` or `slow` such as `--mode fast` or `--mode slow`)
* **Default Values**: Although not specifically provided by `clap` you can achieve this exact functionality from Rust's `Option<&str>.unwrap_or("some default")` method (or `Result<T,String>.unwrap_or(T)` when using typed values)
* **Automatic Version from Cargo.toml**: `clap` is fully compatible with Rust's `env!()` macro for automatically setting the version of your application to the version in your Cargo.toml. See `examples/09_AutoVersion.rs` for how to do this (Thanks to [jhelwig](https://github.com/jhelwig) for pointing this out)
* **Typed Values**: You can use several convenience macros provided by `clap` to get typed values (i.e. `i32`, `u8`, etc.) from positional or option arguments so long as the type you request implements `std::fmt::FrmStr` See the `examples/12_TypedValues.rs` or the [documentation](http://kbknapp.github.io/clap-rs/docs/clap/index.html) for more information.
* **Typed Values**: You can use several convenience macros provided by `clap` to get typed values (i.e. `i32`, `u8`, etc.) from positional or option arguments so long as the type you request implements `core::str::FromStr` See the `examples/12_TypedValues.rs` or the [documentation](http://kbknapp.github.io/clap-rs/docs/clap/index.html) for more information.
