+# Perl script to check for matching of JNI interfaces to implementation.
+# We check all .cpp arguments and .h arguments and make sure that for
+# each .h declaration (marked by JNIEXPORT keyword), there is a .cpp
+# definition for the same function (also marked by JNIEXPORT keyword),
+# and vice versa.  Definitions and declarations are determined solely
+# by whether they are in a .h or .cpp file - we don't do any further
+# analysis.
+#
+# Some additions made to help with Berkeley DB sources:
+#
+#   Berkeley DB Java sources use JAVADB_*_ACCESS #defines
+#   to quickly define routine access functions.
