Major version update

Official websites do not use .rip
We are an unofficial archive, replace .rip by .gov in the URL to access the official website. Access our document index here.

We are building a provable archive!
A lock ( Dot gov ) or https:// don't prove our archive is authentic, only that you securely accessed it. Note that we are working to fix that :)
