-where <source>* is zero or more source descriptions (e.g., mbox
-filenames on disk, or imap/imaps URIs).
-
-If the sources listed are not already in the Sup source list,
-they will be added to it, as parameterized by the following options:
- --archive: messages from these sources will not appear in the inbox
- --unusual: these sources will not be polled when the flag --the-usual
- is called
-
-Regardless of whether the sources are new or not, they will be polled,
-and any new messages will be added to the index, as parameterized by
-the following options:
- --force-archive: regardless of the source "archive" flag, any new
- messages found will not appear in the inbox.
- --force-read: any messages found will not be marked as new.
-
-The following options can also be specified:
- --the-usual: import new messages from all usual sources
- --rebuild: rebuild the index for the specified sources rather than
- just adding new messages. Useful if the sources
- have changed in any way *other* than new messages
- being added.
- --force-rebuild: force a rebuild of all messages in the inbox, not just
- ones that have changed. You probably won't need this
- unless William changes the index format.
- --optimize: optimize the index after adding any new messages.
- --help: don't do anything, just show this message.
