These are special articles written to comply with NuVoc standards, and tagged: Category:NuVoc.
They explain principles and practice in greater depth than appropriate on the primitives' pages themselves (all tagged: CategoryVoc), or which are relevant to more than one page.
They are task-oriented rather than function-oriented
- i.e. they describe features from the point-of-view of what the reader wants to achieve, rather than document J's functionality (as the primitive-pages do)
These pages are linked from the primitive-pages themselves, at the point where they are relevant.
