The description I don't think needs to be any more descriptive, it's clear this is a dependency resource for modders to add custom transfer reasons to your cities. Unless a mod utilizes this dependency, or you're a modder yourself, you wont find any use in this.
"{
MealsDeliveryLow = 0, // deliver low end food
MealsDeliveryMedium = 1, // deliver regular food
MealsDeliveryHigh = 2, // deliver high end food
FoodSupplies = 3, // food materials for restaurants
DrinkSupplies = 4, // drink materials for restaurants
Bread = 5, // bread
CannedFish = 6, // canned fish
PoliceVanCriminalMove = 7, // carry prisoners from small police stations to big ones
PrisonHelicopterCriminalPickup = 8, // pick up from big police stations
PrisonHelicopterCriminalMove = 9, // transfer to prison
MealsLow = 10, // serve low end food
MealsMedium = 11, // serve normal food

The source code is linked (thank you author!) and you can easily skim through to get a quick idea of the functionality.

i agree need some more info please

It's a dependency for other mods. For example for the "Prison Helicopter Mod"

A mystery that goes unanswered, maybe the author does not know :)

Sooooo, what does it do?

Looking at the description I have no idea what this is for or what it does.

A dependency for the Prison Helicopter Mod now.

SKYVE would say: the description is too short...
