+# 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',
+#   }
+#
