# Auto Common Utilities
## Overview
The Auto project has a set of common utilities to help ease use of the
annotation processing environment.
## Utility classes of note
* MoreTypes - utilities and Equivalence wrappers for TypeMirror and related
subtypes
* MoreElements - utilities for Element and related subtypes
* SuperficialValidation - very simple scanner to ensure an Element is valid
and free from distortion from upstream compilation errors
* Visibility - utilities for working with Elements' visibility levels (public,
protected, etc.)
* BasicAnnotationProcessor/ProcessingStep - simple types that
- implement a validating annotation processor
- defer invalid elements until later
- break processor actions into multiple steps (which may each handle
different annotations)
## Usage/Setup
Auto common utilities have a standard [Maven](http://maven.apache.org) setup
which can also be used from Gradle, Ivy, Ant, or other systems which consume
binary artifacts from the central Maven binary artifact repositories.
```xml
<dependency>
