KEYWORDS: VIRUS MERRYXMAS VACCINE XMAS PICKLE ANTIBODY INOCULATE

This stack eliminates script based viruses which spread themselves by 
appending the scripts of other stacks with additional instructions which 
in turn infects every stack they come in contact with. The original virus 
of this ilk is called "merryxmas."

Since the appearance of merryxmas, other strains have surfaced such as 
merry2xmas, Lopez and others too crude to mention. merryxmas Vaccine 
catches them all-and it's FREE!

NEW in v3.2
----------
A well meaning merryxmas "antibody" has appeared. Unfortunately, while it 
may have good intentions, it is by definition a virus itself. It doesn't 
do any harm, but it does quietly insert itself into the Home stack and 
others in much the same way merryxmas does. Version 3.2 removes the 
antibody.
 
Requirements
