+ * TABLE GENERATOR
+ * The following part of code is NOT included in the actual server's
+ * or library source, it's just used to build the above tables
+ *
+ * This should rebuild the actual tables and automatically place them
+ * into this source file, note that this part of code is for developers
+ * only, it's supposed to work on both signed and unsigned chars but I
+ * actually tested it only on signed-char architectures, the code and
+ * macros actually used by the server instead DO work and have been tested
+ * on platforms where0 char is both signed or unsigned, this is true as long
+ * as the <limits.h> macros are set properly and without any need to rebuild
+ * the tables (which as said an admin should NEVER do, tables need to be rebuilt
+ * only when one wants to really change the results or when one has to
+ * compile on architectures where a char is NOT eight bits [?!], yes
+ * it all is supposed to work in that case too... but I can't test it
+ * because I've not found a machine in the world where this happens).
+ *
+ * NEVER -f[un]signed-char on gcc since that does NOT fix the named macros
+ * and you end up in a non-ANSI environment where CHAR_MIN and CHAR_MAX
+ * are _not_ the real limits of a default 'char' type. This is true for
+ * both admins and coders.
