Sauron allows you to log variables inside of Unity in a way similair to Androids Logcat.
Features
* Logging with priority, tag and message so you can filter which messages the show, and when.
* Better logging of default variables, like logging arrays and vectors
* Inspect complex variables
Examples
Sauron itself is documented so it is easy to use. Even if it is not completely clear, ExampleScript is loaded with examples that explain the code.
