Just announcing that the package 'spatstat' is now fully covered by a Free Open Source licence.
In previous versions of spatstat, polygon clipping was (optionally) performed using the package 'gpclib'
which has a restricted licence. From spatstat version 1.34-0 onward, polygon clipping is performed
using the package 'polyclip' which is free open source. This means that all uses of spatstat are now
covered by free open source licences.
