How do you remove a remote branch?

[John Szakmeister]

I can't seem to find anything telling me how to delete a remote
branch.  The use case in this scenario, was that we had a long-running
feature development, so we pushed the branch to a server inside a
shared repository for our tool.  Now that we've merged it, I want it
to remove the branch.  Is there a way to do that from the command
line, short of ssh'ing into the box and removing it manually?

Thanks in advance!
