-                                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
-        Unsets the previously configured variable.
