Log message:
Import zsync-0.6.2 into the packages collection.

	zsync is a file transfer program.  It allows you to download a file
	from a remote server, where you have a copy of an older version of the
	file on your computer already.  zsync downloads only the new parts of
	the file.  It uses the same algorithm as rsync.  However, zsync is
	designed for file distribution, with one file on a server to be
	distributed to thousands of downloaders.  zsync requires no special
	server software - just a web server to host the files - and imposes no
	extra load on the server, making it ideal for large scale file
	distribution.

		Client-side rsync - zsync runs on the client side, thus
		avoiding the high server load associated with rsync.

		Rsync over HTTP - zsync provides transfers that are nearly as
		efficient as rsync -z or cvsup, without the need to run a
		special server application.  All that is needed is an
		HTTP/1.1-compliant web server, so it works through firewalls
		and on shared hosting accounts.

		Handling for compressed files - rsync is ineffective on
		compressed files, unless they are compressed with a patched
		version of gzip.  zsync has special handling for gzipped
		files, which enables update transfers of files which are
		distributed in compressed form.
