+Convert mbox to separate maildirs per feed and filter duplicate messages using the
+fdm program.
+fdm is available at: https://github.com/nicm/fdm
+
+fdm config file (~/.sfeed/fdm.conf):
+
+	set unmatched-mail keep
+
+	account "sfeed" mbox "%[home]/.sfeed/mbox"
+		$cachepath = "%[home]/.sfeed/fdm.cache"
+		cache "${cachepath}"
+		$maildir = "%[home]/feeds/"
+
+		# Check if message is in in cache by Message-ID.
+		match case "^Message-ID: (.*)" in headers
+			action {
+				tag "msgid" value "%1"
+			}
+			continue
+
+			# If it is in the in cache, stop.
+			match matched and in-cache "${cachepath}" key "%[msgid]"
+			action {

+		action {
+			# Store to local maildir.
+			maildir "${maildir}%1"
+
+			add-to-cache "${cachepath}" key "%[msgid]"
+			keep
+		}
+
+Now run:
+
+	$ sfeed_mbox ~/.sfeed/feeds/* > ~/.sfeed/mbox
+	$ fdm -f ~/.sfeed/fdm.conf fetch
+
+Now you can view feeds in mutt(1) for example.
