   - Fully compatible with other relational rules (requirements and exclusions) which allows things like requiring the use of a group, or denying the use of a group conditionally
 * **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_auto_version.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::str::FromStr` See the `examples/12_typed_values.rs`. You can also use `clap`s `simple_enum!` or `arg_enum!` macro to create an enum with variants that automatically implements `std::str::FromStr`. See `examples/13a_enum_values_automatic.rs` for details and performs an ascii case insensitive parse from a `string`->`enum`.

 * **Suggestions**: Suggests corrections when the user enter's a typo. For example, if you defined a `--myoption <value>` argument, and the user mistakenly typed `--moyption value` (notice `y` and `o` switched), they would receive a `Did you mean '--myoption' ?` error and exit gracefully. This also works for subcommands and flags. (Thanks to [Byron](https://github.com/Byron) for the implementation) (This feature can optionally be disabled, see 'Optional Dependencies / Features')
 * **Colorized (Red) Errors (Non Windows OS only)**: Error message are printed in red text (this feature can optionally be disabled, see 'Optional Dependencies / Features').
 * **Global Arguments**: Arguments can optionally be defined once, and be available to all child subcommands.
