+# This script generates a AUTHORS file in the current directory based on the
+# output of the git log command. It splits the contributors in 2 groups:
+#  * The "active contributors" are the contributors that authored commits over the last 2 years
+#  * The "retired contributors" are the contributors that have authored commits but not over the last 2 years
+# ###########################################################################################################
+
+# This map is used to map the old authors to the new ones to avoid duplicates
