The changelogstat command options synopses describe arguments with text rather than using placeholders as other commands do.
For example, this is the current online help output for dump-change-number-db:
$ ./opendj/bin/changelogstat dump-change-number-db --help Usage: changelogstat {options} dump-change-number-db {options} Dump the change number DB Global Options: See "changelogstat --help" SubCommand Options: --from The upper bound of change number range The lower bound of the range of change numbers to dump --outputDir The output directory The output directory for the dump files --to The upper bound of change number range The upper bound of the range of change numbers to dump
If the online help followed the conventions of the other tools, the help would look more like this:
$ ./opendj/bin/changelogstat dump-change-number-db --help Usage: changelogstat {options} dump-change-number-db {options} Dump the change number DB Global Options: See "changelogstat --help" SubCommand Options: --from {number} The lower bound of the range of change numbers to dump --outputDir {directory} The output directory for the dump files --to {number} The upper bound of the range of change numbers to dump
