# 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.
