Let's remove lines 22-24.  They are a little confusing.

[mattm, 2011/11/08 02:12:27]

Done.  (did you mean just in the header or in the .cc too?)

[wtc, 2011/11/08 23:21:18]

I meant just in the header.

These three people contributed ECC code to NSS.  The
declaration of this function is not ECC specific, and
this header is intended to declare all or most functions
we copied from NSS, so it isn't necessary to acknowledge
the ECC contributors in this header.

On the other hand, pk11akey.cc has ECC related code, so
we should acknowledge the ECC contributors.

If you rename this header to something more generic like
chromium-nss.h or chromium-pk11pub.h, this comment should
be updated.
