"""
SoftLayer external inventory script.
The SoftLayer Python API client is required. Use `pip install softlayer` to install it.
2017-01-28 00:20:31 +01:00
You have a few different options for configuring your username and api_key. You can pass
environment variables (SL_USERNAME and SL_API_KEY). You can also write INI file to
~/.softlayer or /etc/softlayer.conf. For more information see the SL API at:
- https://softlayer-python.readthedocs.io/en/latest/config_file.html
The SoftLayer Python client has a built in command for saving this configuration file
via the command `sl config setup`.
