augeas-lenses 1.6.0-0ubuntu1 (armhf binary) in ubuntu yakkety

 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.
