Fetch entries from given categories only

[UrsKR]

MediaWiki has a helpful concept called category, which, when used correctly and diligently by editors links all pages so categorized under an umbrella page.
For larger wikis with diverse topics, it would be great to filter the entries by category before creating the dictionary, so less-helpful entries are skipped.

e.g. using my perennial example, BattleTechWiki at sarna.net, I would like to exclude all pages discussion novels and real-world-people so my dictionary only contains in-universe definitions.

Hmm I like this suggestion. Would be cool to populate the list of categories in the pregeneration step and allow users to uncheck certain ones.

Definitely seems doable.
