+# This script updates the READMEs with the latest non-SNAPSHOT version number and increments the SNAPSHOT 
+# version number in the pom.xml files.
+
+# Precondition: the version in pom.xml does not contain "SNAPSHOT" before running this script.  
+# Argument (optional):
+#   $1: new version number for pom.xml files (do not include -SNAPSHOT, that is done automatically).
+#   Providing no argument defaults to incrementing revision number from x.y.z-SNAPSHOT to x.y.z+1-SNAPSHOT
+
+# Example: Suppose that before running this script, the pom reads 7.8.9-SNAPSHOT.  This script will replace 
+# all occurrences of #.#.# with 7.8.9 in the README files and the first occurrence of 7.8.9-SNAPSHOT with 
+# 7.8.10-SNAPSHOT in the pom.xml files.
