+ * Nothing in this file is intended to be modified or adjusted by the

+ *
+ * If you think that something actually needs to be changed, adjusted
+ * or fixed in this file, then, report it on the c-ares development
+ * mailing list: http://cool.haxx.se/mailman/listinfo/c-ares/
+ *
+ * This header file shall only export symbols which are 'cares' or 'CARES'
+ * prefixed, otherwise public name space would be polluted.
+ *
+ * NOTE 2:
+ * -------
+ *
+ * Right now you might be staring at file ares_build.h.in or ares_build.h,
+ * this is due to the following reason:
+ *
+ * On systems capable of running the configure script, the configure process
+ * will overwrite the distributed ares_build.h file with one that is suitable
+ * and specific to the library being configured and built, which is generated
+ * from the ares_build.h.in template file.
