In the long run, we want to support providing config files to specify the workflow and parameters.

Usage options:

python -m webs.run {app} {args}
python -m webs.run {app} /path/to/config.toml

In this case, there's two positional arguments, app which is required and config which is optional.

I also don't think it's necessarily the case that we need to support all options in the CLI.

We need to support the following:

• Provide config file to CLI
• Merge config file with CLI options to create global config
• Save global config to file in run directory
• Have a mechanism for create subconfigs for different aspects of the workflow.
