===Lists===
The function relies on three lists to accomplish its task.  These lists are:
#<code>ship_prefix_list</code> – a list of commonly used ship prefixes initially taken from {{tlx|ship prefix}}; these are usually, but not always wholly uppercase
#<code>nationality_list</code> – a list of nation names in their adjectival form; these are always capitalized; always one or two words
#<code>ship_type_list</code> – a list ship-type descriptor phrases; these are usually, but not always wholly lowercase; always one to two words

To add to any of these lists, the form is:
:<code><nowiki>['</nowiki>''addition''<nowiki>'] = true,</nowiki></code>
the trailing comma is important. See the instructions that accompany each list for limitations and implementation details.
