Augeas is a configuration editing tool. It parses configuration files in their native formats and transforms them into a tree. Configuration changes are made by manipulating this tree and saving it back into native config files.

• An API provided by a C library
• A command line tool to manipulate configuration from the shell (and shell scripts)
• Language bindings to do the same from your favorite scripting language
• Canonical tree representations of common configuration files
• A domain-specific language to describe configuration file formats

• Manipulate configuration files safely, safer than the ad-hoc techniques generally used with grep, sed, awk and similar mechanisms in scripting languages
• Provide a local configuration API for Linux
• Make it easy to integrate new config files into the Augeas tree
