Augeas lenses documentation
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). . This package contains the generated documentation for the lenses shipping in the augeas-lenses package.
