+=item --no-index
+
+Disables Xapian and overview DB indexing on the new inbox.
+By default, public-inbox-convert creates a new index in the
+v2 inbox and indexes all existing messages, a lengthy
+operation for large inboxes.
+
+=item -j JOBS, --jobs=JOBS
+
+Control the number of indexing jobs and Xapian shards of the v2
+inbox. By default, this is the detected CPU count but capped
+at 4 due to various bottlenecks. The number of Xapian shards
+will be 1 less than the JOBS value, since there is a single
+process which distributes work to the Xapian shards.
