Updating a design doc using curl

[Rajkumar S]

Hi,

I have a design doc by name score_list which I edit using my normal
editor and use curl to upload it to couch.

curl -X PUT "http://myserver:5984/mydb/_design%2Fscore_list"; -H
"Content-Type: application/json" -T score_list.js

{"ok":true,"id":"_design/score_list","rev":"528497097"}

After every update I manually copy the rev: from the curl output to
the score_list.js.
{
    "_id": "_design/score_list",
    "_rev": "528497097",
    "language": "javascript",
    "views": {
        "score_list": {
            "map": "function(doc) {\n  emit(null, doc);\n}"
        }
    }
}

This is pretty tedious and error prone and I would like to just update
the design doc and not worry about having correct _rev. Is that
possible? Is there a recommended work flow for editing and updating
design docs?

with regards,

raj
