I usually don't bother with the import script but just do things manually. I keep a text file handy to setup free vs. nonfree:

$ cat nonfree_env

export CVSROOT=:ext:hobbes1069@cvs.rpmfusion.org:/cvs/nonfree

export CVS_RSH=ssh

export CVSTREE=nonfree

export PLAGUE_CLIENT_CONFIG=~/.plague-client-rpmfusion.cfg

Then when I'm ready to do a cvs checkout:

$ source nonfree_env

$ cvs co steam

$ cd steam/devel

$ make new-sources FILES="/path/to/source"

etc...
