Introduction

What is augeas-lenses
augeas-lenses is:
Augeas parses configuration files described in lenses into a tree structure,
which it exposes through its public API. Changes made through the API are
written back to the initially read files.
Lenses are the building blocks of the file <-> tree transformation; they
combine parsing a file and building the tree (the get transformation), with
turning the tree back into an (updated) file (the put transformation).
The transformation works very hard to preserve comments and formatting
details. It is controlled by “lens’’ definitions that describe the file
format and the transformation into a tree. This package includes the official
set of lenses.
