# Zuse

Documentation for the `%base` desk's `/sys/zuse.hoon` library, which contains helper functions for the kernel.

Zuse is the farthest downstream component of the kernel in terms of dependency, so its version number is used to represent the version of the kernel as a whole. For example, a new kernel release might be referred to as "410k" to refer to Zuse kelvin version 410.
