+The notmuch insert command reads a message from standard input,\r
+writes it to a Maildir folder, and then incorporates the message into\r
+the notmuch database. Essentially it moves the functionality of\r
+notmuch-deliver into notmuch.\r
+\r
+Though it could be used as an alternative to notmuch new, the reason\r
+I want this is to allow my notmuch frontend to add postponed or sent\r
+messages to the mail store and notmuch database, without resorting to\r
+another tool (e.g. notmuch-deliver) nor directly modifying the maildir.\r
