+# Definition: augeas::lens
+#
+# Deploy an Augeas lens (and its test file).
+# Check the lens (and run the unit tests) automatically and remove the files if
+# the checks fail.
+#
+# Parameters:
+# ['ensure'] - present/absent
+# ['lens_source'] - the source for the lens
+# ['test_source'] - optionally, the source for the test file.
+# ['stock_since'] - optionally, indicate in which version of Augeas
+# the lens became stock, so it will not be deployed
+# above that version.
+#
+# Example usage:
+#
+# augeas::lens { 'networkmanager':
+# lens_source => 'puppet:///modules/networkmanager/lenses/networkmanager.aug',
+# test_source => 'puppet:///modules/networkmanager/lenses/test_networkmanager.aug',
+# stock_since => '1.0.0',
+# }
+#
