+This is a rewrite of munin node in C.
+
+Pro:
+----
+
+The purpose is multiple:
+
+ * reducing resource usage for embedded plateforms, specially when paired
+   with the C rewrite of the core plugins.
+
+ * no need for Perl
+
+ * Everything runs from inetd.
+
+Cons:
+-----
+
+ * You lose flexibility
+
+      It is compiled code, so you have to create binaries.  Even one for each
+      architecture.
+
+ * Not all the features are implemented
+
+     - root uid is not supported. All plugins are run with a single user, usually nobody.
+     - no socket is opened. Everything runs from inetd.
