Howto read a yaml file

I would like to read a yaml configuration for processing, e.g. a commented version may look like:

absolute_urls: false                        # Absolute or relative URLs for `base_url`
timezone: ''                                # Valid values: http://php.net/manual/en/timezones.php
default_locale:                             # Default locale (defaults to system)
param_sep: ':'                              # Parameter separator, use ';' for Apache on windows
wrapped_site: false                         # For themes/plugins to know if Grav is wrapped by another platform
reverse_proxy_setup: false                  # Running in a reverse proxy scenario with different webserver ports than proxy
proxy_url:                                  # Configure a manual proxy URL for GPM (eg 127.0.0.1:3128)

  translations: true                        # Enable translations by default
  translations_fallback: true               # Fallback through supported translations if active lang doesn't exist
  session_store_active: false               # Store active language in session

  name: grav-site                           # Name prefix of the session cookie. Use alphanumeric, dashes or underscores only. Do not use dots in the session name
  secure: false                             # Set session secure. If true, indicates that communication for this cookie must be over an encrypted transmission. Enable this only on sites that run exclusively on HTTPS
  httponly: true                            # Set session HTTP only. If true, indicates that cookies should be used only over HTTP, and JavaScript modification is not allowed.

I'm thinking about using a complex data reader, but on the other hand it's well sctructed like json or xml.

Does anyone already tried this? Solutions or suggestions welcome :)

Thanks
