 <p><strong>Each plugin must have only one matching non-regex entry.</strong> If multiple non-regex entries exist with the same <code>name</code> value, all but the first will be ignored. A plugin may match any number of regex entries though, and their metadata will be merged, with later entries being merged into earlier entries as detailed in the table below. Merging only takes place if both entries have their <code>enabled</code> value set to <code>true</code> (which is the default if unspecified).
