// This script will cause a store's finite inventory
// and limited gold to be (partially) replenished
// after a certain amount of time passes. It will also
// clean out new items and excess gold. I call this
// restocking.
//
// The timer starts when the store is first opened
// after server rest or the last restock. The time
// is random, but will be at least RESTOCK_TIME_FIXED
// real-time hours. The random component of the time
// is added to this minimum, and will range from 0
// to RESTOCK_TIME_VARIABLE minutes.
//
// Items are only replaced if all of that type have
// been sold (and not bought back). The chance for an
// item to be replaced is RESTOCK_CHANCE.
//
// Items not in the store's original inventory have a
// chance to be removed (sold to unspecified NPC's, if
// you will) when the store restocks. This chance is
// UNSTOCK_CHANCE.
//
// After the store restocks, the store's gold supply -- if
// limited -- will be no more than GOLD_MAX_FRACTION times
// its starting value.
//
// After the store restocks, the store's gold supply -- if
// limited -- will be no less than GOLD_MIN_FRACTION times
// its starting value.
//
// If you try to mess with things and make GOLD_MAX_FRACTION
// less than GOLD_MIN_FRACTION, you deserve whatever happens.
// You may also smack yourself for making trouble. :)

//::////////////////////////////////////////////////////////////////////////////
//
// The variables mentioned above are set globally below.
// In addition, you can change the value for a particular
// store by setting a local variable of the same name
// (and type) on the store.
// NOTE: These variables must be set on the *store*, not
// the merchant.

//
// This script will (likely) break if you switch a
// store from unlimited gold to limited gold through
// scripting. Don't do that. There would be no
