+pt-upgrade compares query execution on two hosts by executing queries in the
 given file (or STDIN if no file given) and examining the results, errors,
 warnings, etc.produced on each.
 
 Execute and compare all queries in slow.log on host1 to host2:
 
-  mk-upgrade slow.log h=host1 h=host2
+  pt-upgrade slow.log h=host1 h=host2
 
 Use mk-query-digest to get, execute and compare queries from tcpdump:
 
   tcpdump -i eth0 port 3306 -s 65535  -x -n -q -tttt     \
     | mk-query-digest --type tcpdump --no-report --print \
-    | mk-upgrade h=host1 h=host2
+    | pt-upgrade h=host1 h=host2
 
 Compare only query times on host1 to host2 and host3:
 
-  mk-upgrade slow.log h=host1 h=host2 h=host3 --compare query_times
+  pt-upgrade slow.log h=host1 h=host2 h=host3 --compare query_times
 
 Compare a single query, no slowlog needed:
 
-  mk-upgrade h=host1 h=host2 --query 'SELECT * FROM db.tbl'
+  pt-upgrade h=host1 h=host2 --query 'SELECT * FROM db.tbl'
