+This modifies notmuch hello to use the new count --batch\r
+functionality. It should give exactly the same results as before but\r
+under many conditions it should be much faster. In particular it is\r
+much faster for remote use.\r
+\r
+The code is a little ugly as it has to do some working out of the\r
+query when asking the query and some when dealing with the result.\r
+However, the code path is exactly the same in both local and remote\r
+use.\r
+---\r
+\r
+It's a little ugly but seems to work and does give a useful speedup.\r
+\r
+Best wishes\r
