Mercurial clone without history

I'm trying to download the source code for a large open source project, so I can look at it.

It says to do:

hg clone http://server/path

However, this is taking forever (I'm assuming because it's a large project). I don't really care about the changesets; I ju开发者_StackOverflowst want the head, and I'm not going to be committing anything.

Is there any way I can just that, without everything else?

Often, when you just point your browser to the repository URL, you can grab a tarball of any revision you like, inluding head. This feature has to be enabled on the server side, though.
