A simple logger built on top of [env_logger](https://docs.rs/env_logger).
It is configured via an environment variable and writes to standard
error with nice colored output for log levels.

## Usage

Add the dependency to your `Cargo.toml`:

```toml
[dependencies]
log = "0.4"
pretty_env_logger = "0.4"
```

Add some usage to your application:

```rust
extern crate pretty_env_logger;
#[macro_use] extern crate log;

fn main() {
    pretty_env_logger::init();
    info!("such information");
    warn!("o_O");
    error!("much error");
}
```

Then run your app with the environmental variable set:

```
RUST_LOG=trace cargo run
```
