"\
Dump modes currently supported by the --dump option:\n\
\n\
benchmark\n\
+ Dump the benchmark structure (set-logic, push/pop, queries, etc.), but\n\
does not include any declarations or assertions. Implied by all following\n\
modes.\n\
\n\
declarations\n\
+ Dump user declarations. Implied by all following modes.\n\
\n\
raw-benchmark\n\
+ Dump all user-commands as they are received (including assertions) without\n\
any preprocessing and without any internally-created commands.\n\
\n\
skolems\n\
+ Dump internally-created skolem variable declarations. These can\n\
arise from preprocessing simplifications, existential elimination,\n\
and a number of other things. Implied by all following modes.\n\
\n\
assertions\n\
+ Output the assertions after preprocessing and before clausification.\n\
Can also specify \"assertions:pre-PASS\" or \"assertions:post-PASS\",\n\
where PASS is one of the preprocessing passes: definition-expansion\n\
boolean-terms constrain-subtypes substitution bv-to-bool bool-to-bv\n\
strings-pp skolem-quant simplify static-learning ite-removal\n\
repeat-simplify rewrite-apply-to-const theory-preprocessing.\n\
PASS can also be the special value \"everything\", in which case the\n\
assertions are printed before any preprocessing (with\n\
\"assertions:pre-everything\") or after all preprocessing completes\n\
(with \"assertions:post-everything\").\n\
\n\
clauses\n\
+ Do all the preprocessing outlined above, and dump the CNF-converted\n\
output\n\
\n\
t-conflicts\n\
+ Output correctness queries for all theory conflicts\n\
\n\
t-lemmas\n\
+ Output correctness queries for all theory lemmas\n\
\n\
t-explanations\n\
+ Output correctness queries for all theory explanations\n\
\n\
bv-rewrites\n\
+ Output correctness queries for all bitvector rewrites\n\
\n\
theory::fullcheck\n\
+ Output completeness queries for all full-check effort-level theory checks\n\
\n\
Dump modes can be combined by concatenating the above values with \",\" in\n\
between them. Generally you want raw-benchmark or, alternatively, one from\n\
the assertions category (either assertions or clauses), and perhaps one or more\n\
other modes for checking correctness and completeness of decision procedure\n\
implementations.\n\
\n\
The --output-language option controls the language used for dumping, and\n\
this allows you to connect CVC4 to another solver implementation via a UNIX\n\
pipe to perform on-line checking. The --dump-to option can be used to dump\n\
to a file.\n\
