based on the work of Bas Couwenberg (2015) I prepared for upload
node-blob as per this ITP:
https://bugs.debian.org/781478, this is the repo:
node-blob is required for node-engine.io-parser (#781458), which in turn
is required for node-socket.io (#707166) which in turn is one of
the bits required by etherpad-lite.
Please someone more experienced than me review it and if it's OK sponsor
