hi folks the following list includes a provides('html' helper function. What are these helper functions? Is there documentation/a reference guide of all helper functions somewhere? Are they specific to couchdb, specific to lists? { "_id": "_design/listtest", "_rev": "22-31ba90b5d72287897d5013a76c08c2c9", "lists": { "foo": "function(head, req) { var out = req.headers.Host ; var row; while (row = getRow()) { (out = out + row.value + '') };return out; }", "bar": "function() { return 'zoom!' }", "bas": "function(head, req) {provides('html', function() {send('');var row;while (row = getRow()) {send(row.value + '
');}return '';});}" } } thanks
