turtle-1.3.1: Shell programming, Haskell-style

# turtle-1.3.1: Shell programming, Haskell-style

`turtle` is a reimplementation of the Unix command line environment in Haskell so that you can use Haskell as both a shell and a scripting language.

Features include:

- Batteries included: Command an extended suite of predefined utilities
- Interoperability: You can still run external shell commands
- Portability: Works on Windows, OS X, and Linux
- Exception safety: Safely acquire and release resources
- Streaming: Transform or fold command output in constant space
- Patterns: Use typed regular expressions that can parse structured values
- Formatting: Type-safe `printf`-style text formatting
- Modern: Supports `text` and `system-filepath`

`turtle` is designed to be beginner-friendly, but as a result lacks certain features, like tracing commands. If you feel comfortable using `turtle` then you should also check out the `Shelly` library which provides similar functionality.
