 44:  * other part of the application with incompatibilities. For this reason,

 48:  * switch to the new self-contained updater utility).
 49:  *
 50:  * References to the application singleton and controller are thus accompanied
 51:  * by or wrapped in a slew of conditional statements for purposes of backwards
