Digital BW, The Print

I've been having a lot of fun experimenting with QTR (on OSX)... so much
fun that I've now got quite a few not-quite-what-I-intended curves
installed.  Is there an easy way to tidy some of them away?  (The
install script seems to be doing some brain surgery on system printing
configuration files that I am reluctant to try to undo by hand!)

Thanks,
