 Preamble
 
 CERN has developed this licence to promote collaboration among
 hardware designers and to provide a legal tool which supports the
 freedom to use, study, modify, share and distribute hardware designs
 and products based on those designs. Version 2 of the CERN Open
 Hardware Licence comes in three variants: CERN-OHL-P (permissive); and
