Deleting files?

[Mike Mellor]

Is it possible for me to delete a working file, but keep it in (for  
lack of a better term) the repository?  For example, I want to be  
able to delete a file now, but be able to "undelete" it some time in  
the future.  The reason that I want to do this is to create a bzr  
repository on a firewire drive, check it out onto my laptop, and  
delete the files that I don't want now (while keeping them on the  
firewire drive).  I know I can do this with subversion, but I really  
enjoy working with bazaar more!

Thanks.
Mike
