#169 INSTALL URL is a dead link

[Yossi]

On http://s3tools.org/download we read: S3cmd requires Python 2.6 (or newer). S3cmd is not compatible with Python 3.x See the INSTALL file contained in the download for installation instructions.

The INSTALL is a link to https://github.com/s3tools/s3cmd/blob/master/INSTALL. However, that URL gives "This webpage is not available."
