The facilities can roughly be grouped as:

1) Facilities for groupwise computations of summary statistics and
other facilities for working with grouped data: 'do' something to data
stratified 'by' some variables.

2) LSmeans (least-squares means), general linear contrasts.

3) Miscellaneous other utilities.
