The Civ4ProcessInfo file defines what commerce types can be created from production in a city (by default, 100% of production to wealth, research, and culture). This can also be used to create an option to have a city build nothing (by setting all of the commerce types so that no production is applied to them).
All tags must be opened and closed; the first is the "open", the second the "close" tag. If nothing goes inside a "list tag", then it should just be the opening tag with a "/" before the closing bracket. The following tables contain all available tags, as well as their purpose and accepted values.
In the following example of code, please note that there is a specific order of all of the tags. You must list the tags in this order for the game to properly interpret your file.
