+#Plugin created by:
+# Stephen Hodgson
+# Malone College - CPSC
+
+#This script is provided as-is with no warranty or guarantee of any kind.
+
+#-This simple plugin figures out how many users are logged into the linux box and writes it to a simple Gauge-style graph.
+#-The plugin takes advantage of the linux 'who' command.
+# -The who command is cut into the first field (to the first space).
+#  -This is the username field.
+#   -Unfortunately this will log multiples for the same user if multiple terminals are open.
+#  -Then we need to sort the results since uniq only deals with unique elements next in line to each other.
+#  -We find the uniqe usernames logged on.
+#  -Then wc -l counts how many lines (users) we're left with.
