copyrights must be released pursuant to a GPL v3 copyright restriction. 
(ii) Any Software created independently by the Senate without any 
preexisting licensing restrictions on any of its components shall be 
released under dual licensing and take one of two forms: (a) a BSD 
license, or (b) a GPL v3 license.  The ultimate user of such Software 
shall choose which form of licensing makes the most sense for his or her 
project. 
(iii) Regarding Software containing preexisting copyright restrictions 
other than GPL, the CIO shall make the determination how he or she 
wishes to release such Software.
