  META KEYWORDS

================================================================================

Keyword:      @appears
Description:  Tell where the documentation for an item should be shown.
              Gives the full new name of the item. Must be placed first in
              the block, or immediately after any @module, @class, or @decl's.
Arguments:    <name> [, type]
              Where:
                <name> is an "absolute" name with identifiers separated by dots.
                  It can also be prefixed by 'scope::' where scope is one of
                  the valid scope modules.
                [type] is either "class" or "module" depending on whether the
                  target item should appear as a class or a module. When not
                  present, the choice will be governed by the item's type, as
                  detected by the extractor. Overriding this is only needed for
                  odd special cases such as a module.pmod containing e g:
                    static class _Foo {...};
                    _Foo Foo = _Foo();
Children:     -

                1. The Pike entity in the adjacent code is one method.
                2. All @decl's in the block are methods with the same name as
                   that method. (look at the last example below)
Arguments:    <declaration>
