## What is this?

This utility can be used to check if a node is said to be
[generated][generated-term].

## When should I use this?

You can use this utility to check is generated.
Generated nodes were not in the source of the original file, and thus not
authored by a human.
This info can then be used to not emit lint messages for generated content.

You might also find the utility [`unist-util-position`][unist-util-position]
useful to get clean positional info.
To display positional info to users, use
[`unist-util-stringify-position`][unist-util-stringify-position].
