If I do that, however, R CMD build builds the package adding the .gz
suffix to these files (i.e. I end up with data/*.csv.gz), presumably
because --resave-data is the default, which uses gzip, provided no
BuildResaveData field is present in DESCRIPTION.  Adding
"BuildResaveData: no" to DESCRIPTION solves this.  For package
maintenance it might be easier to leave the uncompressed data/*.csv and
add "BuildResaveData: bzip2" to DESCRIPTION, but then R CMD build
generates data/*.csv.xz with R-devel (2012-03-22 r58801), so something
seems wrong.  Should we simply stick to doing the compression manually
and adding "BuildResaveData: no" to DESCRIPTION?

Thanks,
