Focused crawls are collections of frequently-updated webcrawl data from narrow (as opposed to broad or wide) web crawls, often focused on a single domain or subdomain.
All examples seems to put all code in the main() function, and demonstrate some static condition happening once. However, this does not reflect any real use cases, and I struggle really hard to implement anything actually useful using the HAL (unless of course I would put all logic into the main() function). There should be some examples which shows actual useful use-cases, and not just PoCs.
Similar to how an app can have it's own packages, create another option to the build function that adds a "hal" package. This is a package that only depends on microzig and would be used to write drivers for chips with similar peripherals, Eg. an nrf52 hal.
An application would be able to access the hal via microzig.hal, and with it's access to other microzig namespaces it would be able to do c
