Help Understand Install SQL

[mc12345678]

The install SQL could use a little more explanation within the file for those that are using this. There is really little that is needed to support the image swap; however, at some point there was an added feature incorporated that generates an attribute link. While not well understood, it does require a SQL statement and it appears if executed multiple times will produce multiple instances of the same thing.
While this could be better controlled with an installer, the software doesn't seem to have reached the level of maturity or need to requiring such an installer.
