Augeas (software)
# Augeas (software)

Augeas is a free software configuration-management library, written in the C programming language. It is licensed under the terms of the GNU Lesser General Public License.

Augeas uses programs called lenses (in reference to the Harmony Project) to map a filesystem to an XML tree which can then be parsed using an XPath syntax, using a bidirectional transformation. Writing such lenses extends the amount of files Augeas can parse.

## Bindings

Augeas has bindings for Python, Ruby, OCaml, Perl, Haskell, Java, PHP, and Tcl.

## Programs using augeas

* Certbot, ACME client
* Puppet provides an Augeas module which makes use of the Ruby bindings
* SaltStack provides an Augeas module which makes use of the python bindings
