# Load

Load variables from a JSON file.

### Parameters

* `config_file` (str): The file to load the variables from.
* `unpack` (bool, optional): If `True`, the variables in the JSON file will be unpacked and returned as individual variables. If `False`, the entire contents of the JSON file will be returned as a dictionary. Defaults to `False`.
* `default` (Any, optional): The value to return if the file does not exist or is not a valid JSON file. Defaults to `None`.

### Returns

* `Any`: The variables stored in the JSON file, either as a dictionary or as individual variables, depending on the value of `unpack`. Returns `default` if the file does not exist or is not a valid JSON file.

### Raises

* `IOError`: If there is an error reading from the file.
* `ValueError`: If `unpack` is `True` and the JSON file does not contain a dictionary.

### Example

```python
import pysettings_manager as pysm
# Unpack variables
foo, bar = pysm.load("settings.json", unpack=True)

# Return dictionary
settings = pysm.load("settings.json")
```
