## Setting
- `ZSH_MISE_AUTOEXPORT_VERSIONS`: if set to `true`, the plugin will register a `chpwd` hook to update environment variable to reflect the current configuration. The variables are constructed from the output of `mise -ls -c`, with the `MISE_TOOL_` prefix, and their value is set to the full version of the tool, e.g., `M̀ISE_TOOL_PYTHON=3.8.20``. This can be used when building prompts.
