+ *
+ * For example, let's say that you want to make sure that a given version

+ *
+ * bool IsVersionValid(const char* version) {
+ * return mozilla::Version("15.a2") <= mozilla::Version(version);
+ * }
+ *
+ * Or, since Version's constructor is implicit, you can simplify this code:
+ *
+ * bool IsVersionValid(const char* version) {
+ * return mozilla::Version("15.a2") <= version;
+ * }
+ *
+ * On Windows, if your version strings are wide characters, you should use the
