Augeas is a library for programmatically editing configuration files.
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.

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. All matches are done in fixed positions in the tree, and nothing
matches more than one path segment.r8 r9 r z Error during match procedure!)r( r) r* r. r/ r ZPOINTERr0 r r, Z aug_matchr

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'. The
value of NAME has no meaning.
The 'lens' grandchild of /augeas/load specifies which lens to use, and
can either be the fully qualified name of a lens 'Module.lens' or
'@Module'. The latter form means that the lens from the transform
marked for autoloading in MODULE should be used.
The 'incl' and 'excl' grandchildren of /augeas/load indicate which
files to transform. 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.
When AUG_INIT is first called, it populates /augeas/load with the
transforms marked for autoloading in all the modules it finds.
