By default, jazzy looks for a file named ".jazzy.yaml" in the source
directory and its ancestors. You can override the config file location
with --config.
(The source directory is the current working directory by default.
You can override that with --source-directory.)
The config file can be in YAML or JSON format. Available options are:

.gsub(/^ +/, '')
