Description
	I got sick of balancing my checking account by hand because I
	continually ended up with discrepancies from the bank. So I threw
	together this simple C program to balance my budget.

	It has turned out to be very useful, and as long as I enter
	my transactions, it's much easier to resolve discrepancies
	in sam(1) then on paper.
