	Here are some ideas for changes to Hack that I've made.  
1) Added an option called pickup (on by default).  When off,
	you do not automatically pick up objects when moving onto them;
	you have to use the ',' command to pick objects up.  I find this
	option is very useful when in shops or cleaned out zoos. 
2) Added a scroll of knowledge - it simply adds about 2D6 objects
	to your list of discovered items.
3) The program now stops you from attacking a tame dog by moving
	onto it (unless you are blind).

	Some other ideas I'm thinking about:
1) Making shopkeepers pay higher prices for valueble gems IF you have
	identified them.
2) Allowing you to find out the prices of items before you buy them
	(by extending the Ix command).  This would require some sort of fix
	to make prices consistent.
3) Add a ring of portage - when worn, it increases your carrying capacity.
	
	If I get requests, I'll post the changes, but they are not hard
to figure out.  What other changes are hack wizards out there implementing?
