Description

The current attachment information looks like this:

GET /dbname/docid

"_attachments": {
"jquery-1.4.1.min.js":

{ "content_type": "text/javascript" "revpos": 138 "length": 70844 "stub": true }

}

If a client wanted to sync local files as attachments with a document it would not currently be able to do so without keeping a local store of the revpos. If this information included an md5 hash of the attachment clients could compare it against a hash of the local file to see if they match.
