+.B \-\-body=(true|false)
+
+If true (the default)
+.B notmuch show
+includes the bodies of the messages in the output; if false,
+bodies are omitted.
+.B --body=false
+is only implemented for the json and sexp formats and it is incompatible with
+.B --part > 0.
+
+This is useful if the caller only needs the headers as body-less
+output is much faster and substantially smaller.

+.B \-\-include-html
+
+Include "text/html" parts as part of the output (currently only supported with
+--format=json and --format=sexp).
+By default, unless
+.B --part=N
+is used to select a specific part or
+.B --include-html
+is used to include all "text/html" parts, no part with content type "text/html"
+is included in the output.
