tagging without checkin

[Alex Greif]

Hi,
I want to do the following:
after checking in all changes for a certain version (like version 3.2
of my software) I would like to tag the bazaar tree somehow, so that
in the logs I can see when the version 3.2 was completed. Sure I could
modify a file and do a bzr ci -m "v3.2", but is there a possibility to
do this without a dummy modification and a checkin?

Alex.
