Hello tech-userlevel,

I am participating in GSoC integrating the memory-hard hashing algorithm
argon2 into NetBSD.  I plan on using the following GIT repo for all code,
comments, and issues.  Please feel free to review.  If you find an issue,
please help out and create an Issue.

I am thankful for this opportunity and look forward to working with you all.

Thanks and regards,
Jason
