+   This command is a dumb mail indexer. It can either (1) scan
+   directories containing mbox files, and create a db file containing
+   for each mail a list of fields computed from the header, or (2)
+   read such a db file and get all the mails matching regexp-defined
+   conditions on the fields.
+
+   It is low-tech, simple, light and fast.
