I searched all over the wiki and did not see any description of the sum function that can be called in the reduce method of a view. I can guess what it does but a pointer to more concrete information would be appreciated.
There is only a passing reference to it in the page http://wiki.apache.org/couchdb/Introduction_to_CouchDB_views Are there any other handy functions that could be called from inside map or reduce? Thanks Rangachari Anand
