Revised^6 Report On Algorythmic Language Scheme (r6rs) is a new standard for the SchemeLanguage, which has been officially ratified on August 12, 2007.
There's a site devoted to it: http://www.r6rs.org
The standard is intended to replace the previous one, r5rs (see RevisedFiveReportOnScheme). However, the new standard is so complicated that it is unlikely that InteLib can ever comply to it. We therefore continue to be interested in the older standard, which is in fact no problem to implement.
