 - Sync function merge (master and slave functions are more more or less the same)
 - Tree function merge (current and after tree functions are the same except for output filename and logging)
 - Tree functions execute piped commands (grep, awk) on master when launched on remote slave which can cause more bandwith usage
+- Exit trap function must also kill child processes
+- Make osync run on Cygwin for Windows compatibility

@@ -23,6 +23,8 @@ Osync uses a master / slave sync schema. It can sync local or remote directories
 Also, osync uses pidlocks to prevent multiple concurrent sync processes on/to the same master / slave replica. Be sure a sync process is finished before launching next one.
 You may launch concurrent sync processes on the same system but only for different master replicas.
 
+Currently, it has been tested on CentOS 5, CentOS 6, Debian 6.0.7, Linux Mint 14 and Ubuntu 12.
