I figured you had access to a search engine :)

basically Augeas is a language for describing configuration files so
that they can be parsed into trees and manipulated uniformly.  e.g.,
you could run

  set /files/etc/bacula/bacula-dir.conf/job/foobar-job1/schedule Monday1

or

  set /files/etc/bacula/bacula-dir.conf/director/my-dir/maximumconcurrentjobs 5

don't be mislead by /etc/bacula/bacula-dir.conf -- Augeas will handle
recursively including other files, so this is just the filename of the
starting point.

one nice feature is that it takes comments and whitespace seriously,
so comments are attached to configuration statements and will go away
if the statement is removed.  (obviously, depending on comment style
it can't always do this 100% correctly, but it does its very best.)
