Note that if $HOME/.dvdcss existed, my code still used it, so no data would be 
lost by an upgrade.

However, the basis of Reimar that it "contains essential data" seems
quite weak,
given that it contains a CACHEDIR.TAG file, marking the folder as
containing " cached
information", suggested "to  avoid backing up, archiving, or otherwise
unnecessarily copying such
directories".
Should the folder be described as a "Non-ephemeral cache contaning
essential data which
shouldn't be backed up" ? :)
