# Get or remove a set of WAVE User's Guide figures in the wug-src directory.
# The wug-src directory must be the current directory when this script is run.

# Arrgh!!! Current versions of pnmtops, standard with Redhat Linux 7.3 and
# later, produce incorrect output unless the option -nosetpage is used ... but
# older versions produces no output if -nosetpage is used.  So, let's see which
# version we've got:
