+# 20100310  v1.01  ls
+#               as threatened, shows now "temperatures" of active hosts.deny lines. Recent additions are 
+#               displayed in bright red, turning to blue as older the addition rules are.
+#               This requires denyhosts to add line to hosts.deny in a specific format. Also, times are currently
+#               hardcoded, and not a lot of flexibility adjusting them through parameters.
+#               A line in hosts.deny should come with a comment, looking like:
+#               # DenyHosts: Sat Mar  6 01:11:57 2010 | sshd: 87.101.51.198
+#               8 graphs are drawn from that depicting number of rules in 24 h increments. Different colours are
+#               assigned to graphs which are <24h, 24-48h, 48-72h ... old. The last (coldest) graph shows rules 
+#               which have been added > 168h ago.
+#               I'm considerering to change age granularity to hours, rather than days, and plot many graphs (64 or 128,
+#               which are nice for colour calculations), showing more of a colour cloud than discernible areas. 
+#               The plugin must have permission to read /etc/hosts.deny, of course.
+# 20100308, v1.0, ls 
+#               Will probably add multiple stacked graphs, indicative for addition/removal date of denies,
+#               instead of a boring single area graph.
