-csync - just another tool to harm your system
+WHAT IS CSYNC?
+==============
+
+csync is a lightweight utility to synchronize files between two directories on
+a system or between multiple systems.
+
+It synchronizes bidirectionally and allows the user to keep two copies of files
+and directories in sync. csync uses widely adopted protocols, such as smb or
+sftp, so that there is no need for a server component. It is a user-level
+program which means you don’t need to be a superuser or administrator.
+
