# FILE: cl-dump.pl
#
# SYNOPSIS:
# cl-dump.pl [-h host] [-p port] [-D bind-dn] -w bind-password | -P bind-cert
# [-r replica-roots] [-o output-file] [-c] [-v]
#
# cl-dump.pl -i changelog-ldif-file-with-base64encoding [-o output-file] [-c]
#
# DESCRIPTION:
# Dump and decode Directory Server replication change log
#
# OPTIONS:
# -c Dump and interpret CSN only. This option can be used with or
# without -i option.
#
# -D bind-dn
# Directory server's bind DN. Default to "cn=Directory Manager" if
# the option is omitted.
#
# -h host
# Directory server's host. Default to the server where the script
# is running.
#
# -i changelog-ldif-file-with-base64encoding
# If you already have a ldif-like changelog, but the changes
# in that file are encoded, you may use this option to
# decode that ldif-like changelog.
#
# -o output-file
# Path name for the final result. Default to STDOUT if omitted.
#
# -p port
# Directory server's port. Default to 389.
#
# -P bind-cert
# Pathname of binding certificate DB
#
# -r replica-roots
# Specify replica roots whose changelog you want to dump. The replica
# roots may be seperated by comma. All the replica roots would be
# dumped if the option is omitted.
#
# -v Print the version of this script.
#
# -w bind-password
# Password for the bind DN
#
# RESTRICTION:
# If you are not using -i option, the script should be run when the server
# is running, and from where the server's changelog directory is accessible.
#
# DIAGNOSIS:
# For environment variable issues, see script repl-monitor.pl under bindir
#
