// if located within specific directories. Because NSBundle uses CFBundle
// behind the scenes, this also blocks modules loaded by NSBundle when located
// in those same specific directories.
//
// Blocked modules include input managers, contextual menu items, and
// scripting additions installed in per-user (~/Library), per-machine
// (/Library), or network (/Network/Library) locations. Modules installed in
// the operating system location (/System/Library) are never blocked.

// This mechanism does not prevent CFBundle (or NSBundle) objects from being
// created, but it does block them from loading modules into the process.
// Returns whether the blocking mechanism setup was successful.
