More precisely, blah blah is executed if $EnableRobotCloakActions
is explicitly set to a non-zero (true) value.
This is in contrast to something like
if (IsEnabled($EnableXYZ, 1)) { blah blah }
where blah blah is executed unless $EnableXYZ has been explicitly
set to a zero (false) value.
The purpose of the function is to provide an easy way to specify
a default action without actually setting the configuration variable
(because we may later need to know that the configuration variable
was unset, as opposed to being programmatically set to a default).
