Steps to start a new Launchpad project using Bazaar on Windows

Register Username on Launchpad: https://launchpad.net/+login
Search and then Register Your New Project Name on Launchpad: https://launchpad.net/
Create working folder and add some starter files
Download Standalone Windows Installer for Bazaar and Install Bazaar: http://bazaar-vcs.org/Download
Right-click on folder and select Bzr Here
Navigate into working folder
Type: bzr whoami to find out what bazaar thinks you are.
Type: bzr whoami "Erik Thompson" to tell bazaar exactly who you are.
1. It is often a good idea to include an email address in your bzr identity, for example "Eric the Viking <eric@vikings-r-us.example.com>"
2. If you do this, and the email address is linked to you in Launchpad, then Launchpad is able to link the revisions you created to your Launchpad identity.
Initialize Bazaar (use the 1st time only for a working folder), type: bzr init
If you want to ignore any folders or files type ignore filename
Recursively Add files and folders, type: bzr add
Save the updates locally: bzr commit –m "saving my initial setup"
Register a new branch under your Lanuchpad user name
1. You don't need to register a hosted branch first, you can just push directly to it.
Download puttygen and pageant (http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html) and use puttygen to create a public and private key
Copy the text in the panel that is a bunch of random letters into your launchpad ssh key
Start pageant, and click right click the pageant icon in the system tray, click add-key and select your key. Now bzr should be able to publish to Launchpad.
Upload the code using the example command listed in launchpad under your branch name.
In my case: bzr push bzr+ssh://mrlobster99@bazaar.launchpad.net/~mrlobster99/emol/devel
1. Bazaar comes with a Launchpad plug-in. You can tell bzr about your Launchpad login using the launchpad-login command.
2. If you did bzr launchpad-login mrlobster99 (and you only need to do this once on any given computer) the command would have checked that the identity you used did exist in Launchpad, and that it had an SSH key listed for it. Once you have done this you can use the shorter push command: bzr push lp:~mrlobster99/emol/devel
3. Also, once a branch has been pushed to a particular location, bzr will remember, so subsequent pushes only need the command bzr push.
Assign this branch to the project trunk

Steps to download a project on Launchpad that uses Bazaar with only one branch

Make sure you have Bazaar installed: http://bazaar-vcs.org/Download
Start Bazzar (perhaps by right-clicking a folder and selecting Bzr Here)
To download the latest revision of the emol project type: bzr checkout https://launchpad.net/emol
To download the second revision of the emol project into a folder called 'rev2' type: bzr checkout https://launchpad.net/emol -r 2 rev2

Example of downloading a Launchpad project that has multiple branches

For this example I'm assuming you want to download RasMol (https://launchpad.net/rasmol)

Make sure you have Bazaar installed: http://bazaar-vcs.org/Download
Go to the launchpad code page for the project: https://code.launchpad.net/rasmol/
Observe that Rasmol has three separate branches: Click the one that says 'debian': https://code.launchpad.net/~tpikonen/rasmol/debian
The Download URL is the info that you need to remember: http://bazaar.launchpad.net/~tpikonen/rasmol/debian
Start Bazzar (perhaps by right-clicking a folder and selecting Bzr Here)
Type 'bzr checkout ' followed by the download URL, e.g. type: bzr checkout http://bazaar.launchpad.net/~tpikonen/rasmol/debian
