+# watch_mdbox
+
+This script is intended to be used in conjunction with mswatch [0]. You
+can see an example ~/.mswatchrc in home/mswatchrc.
+
+You should change the paths according to your your setup.

+
+## What does it do?
+
+This script checks for changes in a dbox[1], which is a mailbox format
+introduced by the dovecot IMAP server[2] for handling mail storage more
+efficiently.
+
+When new mail is added to the dbox, watch-mdbox receives an event through
+inotify, parses the path and prints out the notification mswatch needs
+for starting the synchronisation specifically on this mailbox.
