+##Release:
+##Version 1.3
+##Author: Luke Shirnia
+####################################
+#version 1.3 release notes:
+#added total CPU usage for top process and all its threads
+#added server uptime from /proc/uptime
+#load average now pulled from /proc/loadavg rather than 'w' (for compatibility)
+#replaced 'free -m' with values from /proc/meminfo (for compatibility)
+#####################################
+#Version 1.2 Update Notes:
+#Ram usage now in MB
+#removed 'bc' commands and replaced with awk for compatibility reasons
