$script_name for Parse::Win32Registry $Parse::Win32Registry::VERSION

Compares two or more registry files.
Defaults to displaying a summary of the changes where each letter
represents a change (N=NEWER, O=OLDER, A=ADDED, D=DELETED, C=CHANGED).
The long output will display full details of each change.

$script_name <file1> <file2> <file3> ... [<subkey>] [-v] [-x] [-l] [-a]
    -v or --values      display values
    -x or --hexdump     display value data as a hex dump
    -l or --long        show each changed key or value instead of a summary
    -a or --all         show all keys and values before and after a change
