  * Requires PHP 4.3 or later, primarily tested on PHP 5.2.x.
+ *
+ * Notes:
+ * - Possibility for discount can be enabled per section, there is
+ *   no "global" discount for everything, however.
+ *
+ * - Services in $services1_prices have a threshold for quantity
+ *   discount, but services in $services2_prices do not. The total
+ *   service discount % applies to both, too.
+ *
+ * - If "extra" field is set (as it is for services that have some
+ *   additional material costs), the extra price DOES NOT get
+ *   the section discount % applied!!
+ *
+ * - Ammunition, potions and salves sections have a "base" price,
+ *   on top of which specials (more difficult to make, etc.) additional
+ *   price can be set.
