I once did a repository fetch from google using bzr from a svn repo like this
bzr svn-import http://feedparser.googlecode.com/svn/ feedparser
cd feedparser
bzr branch trunk mybranch
cd mybranch
bzr checkout
now the repository svn repo ( http://feedparser.googlecode.com/svn/ ) has some new updates that i want to fetch but since I changed some files in my local repo ( i.e. the bzr repo on my local machine ) how can I fetch and merge the updates with my update using bzr without loosing the update and my changes?
