//! Crate for getting the user's username, realname and environment.
//!
//! ## Getting Started
//! Using the whoami crate is super easy!  All of the public items are simple functions with no parameters that return `String`s (with the exception of `env`, which returns an enum).  The following example shows how to use all of the functions:
//! 
//! ```rust
//! use whoami;
//! 
//! fn main() {
//!     print!(
//!         "--------------------------------------\n\
//!          user's full name (user):              {}\n\
//!          username (username):                  {}\n\
//!          --------------------------------------\n\
//!          host's fancy name (host):             {}\n\
//!          hostname (hostname):                  {}\n\
//!          --------------------------------------\n\
//!          operating system (os):                {}\n\
//!          desktop environment (env):            {}\n\
//!          --------------------------------------\n\
//!          ",
//!         whoami::user(),
//!         whoami::username(),
//!         whoami::host(),
//!         whoami::hostname(),
//!         whoami::os(),
//!         whoami::env(),
//!     );
//! }
//! ```
