### `autoenv_source_parent()`
zsh-autoenv will stop looking for `.autoenv.zsh` files after the first one has
been found. But you can use the function `autoenv_source_parent` to source a
parent `.autoenv.zsh` file from there.
zsh-autoenv will stop looking for `.autoenv.zsh` files upwards after the first
one has been found, but you can use the function `autoenv_source_parent` to
source the next `.autoenv.zsh` file upwards the directory tree from there.
The function accepts an optional argument, which allows to stop looking before
the file system root is reached:
```zsh
autoenv_source_parent ../..
```
