+See :any:`notmuch-search-terms(7)` for details of the supported syntax
for <search-terms>. With no search terms, a dump of all messages in
-the database will be generated. A "--" argument instructs notmuch that
+the database will be generated. A ``--`` argument instructs notmuch that
the remaining arguments are search terms.
Supported options for **dump** include
- ``--gzip``
- Compress the output in a format compatible with **gzip(1)**.
-
- ``--format=(sup|batch-tag)``
- Notmuch restore supports two plain text dump formats, both with one
- message-id per line, followed by a list of tags.
