[Insight-developers] [ISC-BOARD] Re: Licensing question about Insight Toolkit ( VXL / toms / ACM and non-commercial license conflict with BSD license).

[Bill Lorensen]

Luis,

I guess what we are doing is a "good-effort". Patching the 3.16 is a
"better-effort". Before 3.14 would be a "best-effort", but I think
that good or better is "good enough".

This does point out an issue with using 3rd part libraries.
