%description
If the option -dSAFER is used with gswrap, this script uses bwrap
from the "bubblewrap" package to embbedd the final ghostscript
command within a minimal container. For this, a new, completely empty
filesystem namespace on a tmpfs is populated with the required
libraries and files to run the ghostscript command.
