# You just have to run this script. There is nothing to adjust.
# The correct year is detected through the 'date' function
#
# Note that not all files (usually scripts) contain a copyright. A copyright is only
# needed for those files which are part of a SoPlex distribution (see scripts/makedist.sh)
