Seeking git recipe to grab a single file

I want to grab a single file from a remote git repository into the current directory, which is not a git tree. Is there an easy way to do that? I have tried using git-fetch and git-cat-file, without success.

Thanks,

If the remote repo has a gitweb interface than it's simple:
wget 'http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob_plain;h=0451f69353bad4d07de34fd4658f40b805bd467a;f=Kbuild'

Otherwise, there is no simple way to do it yet.
