It basically just tells those robots (googlebot, lycosbot etc) to go away. But the problem is for it to work properly you would need to name the bot itself and the directory you want it to ignore eg the correct syntax for the robot file to do this would be:
User-Agent: spider or bot name
Disallow: the folder or directory you don't want it to index
However the format you're showing ie Disallow: /google/ is usually the syntax used for folders and directories not for user agents (spiders and bots) so it's a little confusing. Unless they have folders named google, lycos etc but as there's no user agent statement shown its hard to say but it looks like they are just folders that they don't want indexed.
