 This plugin adds support for subcategories in addition to article categories.
 
-Subcategories are hierarchical. Each subcategory has a parent, which is either a
-regular category or another subcategory.

 Feeds can be generated for each subcategory, just like categories and tags.

-You can limit the depth of generated subcategories by adjusting the regular expression

-Each subcategory's full name is a `/`-separated list of it parents and itself.

-Each subcategory has an attribute `shortname` which is just the name without
-its parents associated. For example if you had…

-specific subcategory. If you have articles that don't have subcategories these
-values are set to the category slug.
