I'm working on howto document which explains how to create new project 
from scratch. Also I'm planning to create tutorial project as well.
Some thoughts here: http://bazaar-vcs.org/ScmProj/Hello

Some advices about creating new project.

1) You need to create the control dir first:

bzr pinit /some/dir

2) In the /some/dir you'll find .scmproj dir. This is control dir 
(similar to .bzr for usual branches). Step into this dir.

3) You should see there project.cfg file. This is ini-style config file
to describe your project. Basically you need add all your components
in the file with sections like following:

[component "foo"]
RELPATH = path/of/componet/relative/to/project/root
BRANCH_URL = bzr://public/branch/of/your/component/branch

Full description of project.cfg format you could find here:
http://bialix.com/scmproj/docs/project-cfg.html

.scmproj is the (almost) regular bzr branch, so you can commit your
config when you need, and publish it as usual.

4) Then run: `bzr pco --fetch` in the project root and you should
see how component branches fetched from defined URLs and
lightweight checkouts created for them in the project workspace.

5) Use hints and tips from http://bialix.com/scmproj/docs/howto.html
to work with project checkout.

I will be very grateful to any suggestion how to improve the docs.
Or critiques. It helps even more.
