+// IMAP4 connect & synchronise operation control
+// This class deals with stepping through a synchronise operation - this
+// involves:
+// 1. Select inbox
+// 2. Perform any outstanding operations on inbox
+// 3. Synchronise inbox
+// 4. Synchronise folder list
+// 5. Build list of folders to synchronise, sorted by 'last sync' date
+// (oldest first), and outstanding operations (folders with outstanding
+// operations are first, whatever their date).
+// 6. Mirror subscription flags as necessary
+// 7. For each folder in the 'to synchronise' list...
+// i)   Select folder
+// ii)  Perform any outstanding operations
+// iii) Synchronise folder
+// 8. Reselect inbox
+//
