1.-Master Q. vQmod™ is an override system designed to avoid having to change core files. The concept is quite simple... Instead of making changes to the core files directly, the changes are created as xml search/replace script files.
These script files are parsed during page load as each "source" core file is loaded with the "include" or "require" php functions.

2 different objects cannot occupy the exact same space at the same time. That is why it is important that when using search/replace that you match the least amount as possible while still being unique. This will better your chances of something like this:
SELECT * FROM product WHERE product_id = '1' AND status = '1';
If mod 1 wants to change it to:
SELECT * FROM product WHERE product_id = '1' AND model = 'xyz' AND status = '1';
and mod 2 wants to change it to:
SELECT * FROM product WHERE product_id = '1' AND sku = 'xyz' AND status = '1';
Then it is important that both vQmod authors DO NOT try to do:
SELECT * FROM product WHERE p..
