# Demonstrates how to select some messages from one folder, and move
# them to a different folder.  In this case, the first argument is
# the existing folder, the second will contain the messages larger
# than the specified size:
#
#       takelarge.pl infolder outfolder minsize

# *******************************************************************
# * WARNING: the content of infolder will be reduced!!! Don't do this
# *          on your real folders.... it's only a demo
