+    # php cfg.php --name=<configname> [--component=<componentname>] --unset

+
+Options:
+    -h --help                   Print this help.
+    --component=<frankenstyle>  Name of the component the variable is part of. Defaults to core.
+    --name=<configname>         Name of the configuration variable to get/set. If missing, print all
+                                configuration variables of the given component.
+    --set=<value>               Set the given variable to this value.
+    --unset                     Unset the given variable.
+    --shell-arg                 Escape output values so that they can be directly used as shell script arguments.
+    --json                      Encode output list of values using JSON notation.
+    --no-eol                    Do not include the trailing new line character when printing the value.
+
+The list of all variables of the given component can be printed as
+tab-separated list (default) or JSON object (--json). Particular values are
+printed as raw text values, optionally escaped so that they can be directly
+used as shell script arguments (--shell-arg). Single values are displayed with
+trailing new line by default, unless explicitly disabled (--no-eol).
+
+In the read mode, the script exits with success status 0 if the requested value
+is found. If the requested variable is not set, the script exits with status 3.
+When listing all variables of the component, the exit status is always 0 even
+if no variables for the given component are found. When setting/unsetting a
+value, the exit status is 0. When attempting to set/unset a value that has
+already been hard-set in config.php, the script exits with error status 4. In
+case of unexpected error, the script exits with error status 1.
+
+Examples:
+
+    # php cfg.php
+        Prints tab-separated list of all core configuration variables and their values.
+
+    # php cfg.php --json
+        Prints list of all core configuration variables and their values as a JSON object.
+
+    # php cfg.php --name=release
+        Prints the given configuration variable - e.g. \$CFG->release in this case.
+
+    # php cfg.php --component=tool_recyclebin
+    #   Prints tab-separated list of the plugin's configuration variables.
+
+    # export DATAROOT=\$(php cfg.php --name=dataroot --shell-arg --no-eol)
+        Stores the given configuration variable in the shell variable, escaped
+        so that it can be safely used as a shell argument.
+
+    # php cfg.php --name=theme --set=clean
+        Sets the given configuration variable to the given value.
+
+    # php cfg.php --name=noemailever --unset

+Feature: Highlight non-inherited permissions
+  In order that the status of capabilities can be more easily seen
+  As an admin
+  I need altered permissions to be highlighted
+
+  Background:
+    Given the following "courses" exist:
+      | fullname        | shortname   |
+      | Course fullname | C_shortname |
+    And I log in as "admin"
+
+  @javascript
+  Scenario: Override a permission
+    Given I am on "Course fullname" course homepage
+    And I navigate to "Users > Permissions" in current page administration
+    And I select "Manager (0)" from the "roleid" singleselect
+    And I click on "Prohibit" "radio" in the "View added and updated modules in recent activity block" "table_row"
+    And I press "Save changes"
+    And I select "Manager (1)" from the "roleid" singleselect
+    Then the "class" attribute of "View added and updated modules in recent activity block" "table_row" should contain "overriddenpermission"
