A package is a collection of the sort of things you’d place into ~/Library/Application Support/BBEdit/ to extend BBEdit, such as clippings, scripts, language modules, and text filters; but makes it easier to install such items when they are all related to a single type of task, rather than having to manually install and manage items spread out between different folders.
