Augeas parses configuration files into a tree structure, which it exposes through its public API. Changes made through the API are written back to the initially read files. 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. s/ Nathaniel McCallum <nathaniel@natemccallum.com>s� Jeff Schroeder <jeffschroeder@computer.org> Harald Hoyer <harald@redhat.com> - initial python bindings, packaging Nils Philippsen <nils@redhat.com> i����N( t version_info( t reducei t utf8c C s | r | j t � Sd S( N( t encodet AUGENC( t st( ( s* /usr/lib/python2.7/site-packages/augeas.pyt enc: s c C s | r | j t � Sd S( N( t decodeR ( R ( ( s* /usr/lib/python2.7/site-packages/augeas.pyt dec? s c G st g g | D] } t j j | � ^ q D] } | r& | ^ q& } t d � | d � } | sp t d | d � � n | S( s] Search for one of the libraries given as arguments and load it.

The returned paths are sufficiently qualified to make sure that they match exactly one node in the current tree. Path expressions use a very simple subset of XPath: the path 'path' consists of a number of segments, separated by '/'; each segment can either be a '*', matching any tree node, or a string, optionally followed by an index in brackets, matching tree nodes labelled with exactly that string. If no index is specified, the expression matches all nodes with that label; the index can be a positive number N, which matches exactly the Nth node with that label (counting from 1), or the special expression 'last()' which matches the last node with the given label.

Which files to load and what lenses to use on them is specified under /augeas/load in the tree; each entry /augeas/load/NAME specifies a 'transform', by having itself exactly one child 'lens' and any number of children labelled 'incl' and 'excl'.

Their value are used as glob patterns. Any file that matches at least one 'incl' pattern and no 'excl' pattern is transformed. The order of 'incl' and 'excl' entries is irrelevant.
