.: Help for the trash command.

The trash command destroys an item you carry, for good.

It refuses what destroy refuses: cursed items, quest items, a staff with a
focus crystal set in it, and a carrier still holding goods.
A purse or other container with something still inside is refused until you open it.

Usage: 

  trash stick
  This would destroy a stick if you had it in your backpack.
