Chameleon is a Darwin/XNU boot loader based on Apple's boot-132.
Because Chameleon now uses part of GPL V2 licensed code in 2 files, it must conform to the most restrictive license that it uses that is the: GPL Version 2 LICENSE
Chameleon can thus be (and has to be) freely distributed under the term of the GPL V2 license which prevails, as it is the most restrictive license.
