<commit_before>//! Simple script to verify the coding style of this library
//!
//! ## How to run
//!
//! The first argument to this script is the directory to run on, so running
//! this script should be as simple as:
//!
//! ```notrust
//! rustc ci/style.rs
//! ./style src
//! ```
//!
//! ## Guidelines
//!
//! The current style is:
//!
//! * No trailing whitespace
//! * No tabs
//! * 100-character lines
//! * Specific module layout:
//!     1. use directives
//!     2. typedefs
//!     3. structs
//!     4. constants
//!     5. f! { ... } functions
//!     6. extern functions
//!     7. modules + pub use
//!
//! Things not verified:
//!
//! * alignment
//! * 4-space tabs
//! * leading colons on paths
