+    Examples With `ensure => absent`:

+    This type has two behaviors when `ensure => absent` is set.
+
+    One possibility is to set `match => ...` and `match_for_absence => true`,
+    as in the following example:
 
         file_line { 'bashrc_proxy':
           ensure            => absent,
           path              => '/etc/bashrc',
-          line              => 'export HTTP_PROXY=http://squid.puppetlabs.vm:3128',
           match             => '^export\ HTTP_PROXY\=',

+    Note that the `line => ...` parameter would be accepted BUT IGNORED in
+    the above example.
+
+    The second way of using `ensure => absent` is to specify a `line => ...`,

+
