AbstractHTML := 
"This package, previously known as <span class=\"pkgname\">CrystGAP</span>, \
provides a rich set of methods for the computation with affine \
crystallographic groups, in particular space groups. Affine \
crystallographic groups are fully supported both in representations \
acting from the right or from the left, the latter one being preferred \
by crystallographers. Functions to determine representatives of all \
space group types of a given dimension are also provided. Where necessary, \
<span class=\"pkgname\">Cryst</span> can also make use of functionality \
provided by the package <span class=\"pkgname\">CaratInterface</span>.",
