+# sshync is a wrapper around sftp that functions as a Python library alternative to scp
+# openssh (on POSIX compliant Unix) is required
+
+# sshync will always overwrite the older files with the newer files, regardless of all other conditions
+#   ^the age is determined by the date and time of the last modification to the files
+
+# syncing via sshync is always done recursively
