Here's a useful Perl script that finds all of the dictionary keys in the JSPs and the `Messages.properties` file, and prints out keys that are used in the JSPs but aren't in the dictionary, and vice versa. find-unused-keys.pl
Note: slightly out of date, can't detect message keys used in e.g. `LocaleSupportLocaleSupport.getLocalizedMessage()`
You'll need to change the variables at the top of the file to point to your DSpace source dir.
