What is Bazaar?
bzr command cheat sheet
Get Ubuntu Source
Getthe source for a development release branch:
bzr branch ubuntu:<package>
bzr branch ubuntu:jackd2
Or, if you want the source for a specific release:
bzr branch ubuntu:<release>/<package>
bzr branch ubuntu:precise/jackd2
Do not add several features committing them all at once. This makes it hard to oversee changes. A feature change may mean that you edit more than one file though.
To make a commit, you would first make changes. To make new files commitable, you would first need to:
bzr add <yournewfile>
While you'll probably seldom do it this way (if you're working on a debian package), this is how to create a standard bzr commit:
bzr commit -m "a description of your commit"
If you're working on a Debian package, you'll first edit debian/changelog, and then use debcommit. debcommit reads debian/changelog and uses the descriptions of changes from there.
