	# Basically, this adds each variable block, as well
	# as the content that is going to be swapped in said
	# variable block. I may change this later, depending
	# on how I decide to handle looping HTML code in TPL
	# files. The variable blocks, set above, holds all

	# before this will work. Once it has been entered,
	# you can call parse_file('TPL_ID'). This function
	# will search the files variable above for the TPL key
	# and open the .tpl file associated with it, and put
	# it into a variable called $code. It then starts from
	# the first array entry of blocks var above, and
	# replaces any instance of that block with the content
	# associated with it. Whew.
