# This script (leadcheck.sh) was created by WISH Pool and may be distributed
# and modified freely as long as this header section is kept intact.
# The script uses the native cardano-cli executable to calculate leaderlogs.
# You do not need to maintain any database.  You only need the native cardano
# executable cardano-cli.  This should ensure that the script will work with
# future Cardano releases unless there are breaking changes
