			'''curl''' Curl can be used to place data into SWAP.

			To bulk upload a directory, you can use find in conjunction with curl to send lots of files.

			Example: upload a single file (Screenshot.png)
			<pre>
			curl -L -T Screenshot.png http://naraapp13:8080/put/web/test/uploadtest/back5/Screenshot.png
			</pre>

			Example: upload backgrounds to web/test/uploadtest/back5
			<pre>
			find backgrounds -type f -exec curl -L -T {} http://naraapp13:8080/put/web/test/uploadtest/back5/{} \;
			</pre>

			==What happens under the hood.==

			A client only needs to talk to one of the SWAP servers to upload its data. If it attempts to place a file on a server that doesn't belong, that server will issue a redirect and tell the client the correct server to talk to.

			Example: details of the redirect. app13 isn't responsible for the file Screenshot2.jpg, so it issues a redirect to app14 which accepts the file.
