+
+    The \a versionString must have the format x.x.x where each x represents a number
+    of a maximum of 999. If the input format is wrong, -1 will be returned.The first 
+    number will be multiplied by 1000000 the second by 1000 and then all three will
+    be summarized.
+
+    Thus for example 12.5.170 will result in 12005170.
