 107
 108 This module is intended as a shim to ease the eventual transition from
 109 having all barcode-related code in the value builder plugin .pl file
 110 to using C4::Barcodes. Since the shift will require a rather significant
 111 amount of refactoring, this module will return value builder-formatted
 112 results, at first by merely running the code that was formerly in the
 113 barcodes.pl value builder, but later by using C4::Barcodes.
