Bazaar version control - How to

This is a good source for introductions - my favorite list:
"Bazaar uses the following commands for the above functionality.

$ bzr checkout project_trunk_url

This checks out the source code of a project stored at the specified URL.

$ bzr commit

This sends your changes to the shared location, so others can see them. It will display an editor window, where you should enter the summary of your changes. This description will be visible when using the bzr log command.

$ bzr update

This updates your working copy to the latest public revision. Your uncommitted changes are left in place and automatically merged with others' changes. "
