%description
Some enhancements, extensions and additions to the facilities of the
recommended 'MASS' package that are useful mainly for teaching purposes,
with more convenient default settings and user interfaces. Key functions
from 'MASS' are imported and re-exported to avoid masking conflicts.  In
addition we provide some additional functions mainly used to illustrate
coding paradigms and techniques, such as Gramm-Schmidt orthogonalisation
and generalised eigenvalue problems.
