sup-sync [options] <source>*
where <source>* is zero or more source URIs. If no sources are given,
-sync from all usual sources.
-
-Supported source URIs:
- mbox://<path to mbox file>, e.g. mbox:///var/spool/mail/me
- maildir://<path to maildir dir>, e.g. maildir:///home/me/Maildir
- mbox+ssh://<machine>/<path to mbox file>
- imap://<machine>/[<folder>]
- imaps://<machine>/[<folder>]
+sync from all usual sources. Supported source URI schemes can be seen
+by running "sup-add --help".
Options controlling WHICH messages sup-sync operates on:
EOS
opt :changed, "Scan over the entire source for messages that have been deleted, altered, or moved from another source. (In the case of mbox sources, this includes all messages AFTER an altered message.)"
opt :restored, "Operate only on those messages included in a dump file as specified by --restore which have changed state."
opt :all, "Operate on all messages in the source, regardless of newness or changedness."
