With cvs one can export the files that have a specific tag and get no cvs meta data included such as with this command:
cvs -z3 -d:ext:[email protected]:/cvsroot/emle export -R -r BL0123 -d emle030205_BL0123 emle
What is the corresponding bzr command where the launchpad.net branch is lp:emle and the tag is BL0123?
