linux.com has a very nice article on Augeas. It's a very nice overview and introduction.

As embarrassed as I am by the bug the author ran into (blank lines in /etc/hosts threw Augeas' parser off), I am glad to say that it's fixed in the most recent version 0.2.0. The bug and its fix underscores a bigger point though: by basing your config-mangling script on Augeas, rather than parsing files yourself, you will benefit from others finding and fixing bugs in Augeas' parsing logic.

Some of the comments on the article are a little confused about Augeas' purpose: it's not meant for the situations where you'd be perfectly happy to use vi, it's main purpose is to ease scripting configuration changes.
