How do you branch a single file from a multi-file project in bazaar?

Question

How do you branch a single file from a multi-file project in bazaar?

For example:

lp:ubuntu-popey-app has two files; foo.h and bar.h
I would do something like this:

bzr branch lp:ubuntu-popey-app --file "/src/foo.h"

You can use bzr cat, example :

$ bzr cat lp:~ubuntu-clock-dev/ubuntu-clock-app/utopic-3.0/app/ubuntu-clock-app.qml > ubuntu-clock-app.qml 

To get a binary file :

$ bzr cat lp:~ubuntu-art-pkg/ubuntu-themes/trunk/distributor-logo.png  > distributor-logo.png

To get the content of a folder, you can combine bzr ls -R and bzr cat to replicate the folder

$ bzr ls -R lp:~ubuntu-clock-dev/ubuntu-clock-app/utopic-3.0/backend/
