[darcs-users] do we still need libwww support?

Well, it shouldn't be such a problem for camp anyway, due to the
repository format, but the answer is that I will let curl take care of
it:

--------------------------------------------------------
module Main (main) where

import Camp.Network
import System.Environment

main :: IO ()
main = withGlobalCurl $
       withCurl $ \curl -> do
           setSSHPrivateKey curl "/home/ian/.ssh/id_rsa_haskell_darcs"
           setSSHPublicKey curl "/home/ian/.ssh/id_rsa_haskell_darcs.pub"
           setVerbosity curl True
           urls <- getArgs
           let f url = do setURL curl (mkURL url)
                          perform curl
           mapM_ f urls
--------------------------------------------------------

Curl's easy interface will cache 5 connections by default, although you
can change the number (CURLOPT_MAXCONNECTS). I don't think camp will
need more than 1, though.


Thanks
