rust-du
-------
This is just an implementation of `du -sb` in Rust so that I can play around
with learning Rust.
Some things that doing this project allowed me touch on in Rust:
- [Error Handling](https://doc.rust-lang.org/book/error-handling.html)
- with the `try!` macro calls in lib.rs
- with pattern matching inside the main function
- and some `unwrap`s, sprinkled around the place
- Argument Parsing
- with [getopts](https://doc.rust-lang.org/getopts/getopts/index.html)
- Generic Code
- using [AsRef](https://doc.rust-lang.org/book/borrow-and-asref.html)
- Testing
- Packaging
