your choice of licence is easy to understand by humans and computers alike.

Why would you license your design under `CERN-OHL-S v2 or later'? Imagine we
discovered a shortcoming of the licence which made us write a new version, let's
say version 3.0, to fix it. Let us further imagine that we decided to make v3
incompatible with v2 (this actually happened with the GPL). If you licensed your
design under `v2 only' that means it could not be combined with new designs
licensed under v3. If, on the other hand, you license your design under `v2 or
later', you give future licensees the option of interpreting the design as
licensed under the hypothetical v3, and there would be no compatibility issues.
This is quite an important decision to take when you use a reciprocal licence,
so we thought we'd mention it in this guide. You have to make your own judgment
as to whether you believe that CERN can be trusted to ensure that future
versions of the CERN-OHL will be similar in spirit and effect to this version.
