• Switch to DISTVERSION while I am here
• Set EXPIRATION_DATE 2026-10-23
• Pet portclippy
• del.icio.us has been read-only since June 2017 following its acquisition by Pinboard and new posts can no longer be created which makes this module's core write functionality non-functional
• No consumers in the tree
