the tree.
options:
-metas also return trees that include metavariables
-all generate all (lazily)
-all generate all (can be infinitely many, lazily)
-lin linearize result of -all (otherwise, use pipe to linearize)
flags:
-depth generate to this depth (default 3)
-atoms take this number of atomic rules of each category (default unlimited)
-alts take this number of alternatives at each branch (default unlimited)
-cat generate in this category
-old use an older algorithm (usually more memory-consuming)
-nonub don't remove duplicates (faster, not effective with -mem)
-mem use a memorizing algorithm (often faster, usually more memory-consuming)
-lang use the abstract syntax of this grammar
-number generate (at most) this number of trees (also works with -all)
-noexpand don't expand these categories (comma-separated, e.g. -noexpand=V,CN)
