ideviceinstaller tools from https://www.libimobiledevice.org/. Use the HEAD versions from
source; the stable versions have bugs that prevents the Go exec wrapper to install and run
apps.

Second, the Go exec wrapper must be told the developer account signing identity, the team
id and a provisioned bundle id to use. They're specified with the environment variables

Это довольно просто (хотя и не очень полезно), но поможет нам сосредоточиться на том, как работают подзависимости.

## Вторая зависимость, «зависимость» и «зависимая» { #second-dependency-dependable-and-dependant }

Затем можно создать еще одну функцию зависимости, которая одновременно объявляет свою собственную зависимость (таким образом, она тоже является «зависимой»):
