# Description:
# Script to update Java source code headers.
#
# 1) Run from the root of the project (i.e. parent directory of "src"
# 2) Run with no arguments to use the current system date, otherwise provide
# the desired 4 digit YEAR for the copyright end date.
#
# ex:
#
# $ ./update_headers.sh
#
# or
#
# $ ./update_headers.sh 2017
#
# NOTE: Inspect the results of the script by running "git diff" to ensure
# only the headers that should be updated are updated. Currently,
# only these files have a header that should not be overwritten:
#
# src/core/src/main/java/org/locationtech/geogig/plumbing/diff/DiffMatchPatch.java
# src/core/src/main/java/org/locationtech/geogig/storage/datastream/Varint.java
