+  /* \brief Addon versioning using the debian versioning scheme
+
+    AddonVersion uses debian versioning, which means in the each section of the period
+    separated version string, numbers are compared numerically rather than lexicographically,
+    thus any preceding zeros are ignored.
+
+    i.e. 1.00 is considered the same as 1.0, and 1.01 is considered the same as 1.1.
+
+    Further, 1.0 < 1.0.0
+
+    See here for more info: http://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Version
