+Usage: sqlite-csv [options] [<csv>] [<sql-command>]
+
+If no <csv> file is specified, it will be read from stdin.
+If no <sql-command> is specified, uses 'select * from data'.
+If no output format is specified, uses ASCII box rendering.
+
+Options:
+    --csv       output as CSV using a , separator
+    --md        ouput as markdown
+    --json      output as JSON
+    --sep=SEP   use SEP as the column separator when reading the CSV file (e.g. --sep=';')
+    --help      show this message and exit
+
+The imported CSV table is named `data`.
+
+Example: sqlite-csv --md summary.csv 'select * from data order by name'"
+        return
+    end
