The auxiliary trees are mostly located in the buffers prepositions.trees, conjunctions.trees, determiners.trees, advs-adjs.trees, and modifiers.trees,
although a couple of other files also contain auxiliary trees. The
auxiliary trees follow a slightly different naming convention from the
initial trees. Since the root and foot nodes must be the same for the
auxiliary trees, the root nodes are not explicitly mentioned in the
names of auxiliary trees. The trees are named according to the leaf
nodes, starting from the left, and capitalizing the anchor node. All
auxiliary trees begin with a ,
of course. For example,
ARBs, indicates a tree anchored by an adverb (ARB), that
adjoins onto the left of an S node (Note that S must be the foot node,
and therefore also the root node).
