/**
* Our config parser.
*
* Each parser is responsible for creating discover_boot_options from config
* files found on new devices. The boot items discovered during parse will have
* 'resources' attached (see @discover_boot_option), which may already be
* resolved (in the case of a device-local filename, or a URL), or unresolved
* (in the case of a filename on another device).
*
* If the boot option contains references to unresolved resources, the
* device handler will not inform clients about the boot options, as
* they're not properly "available" at this stage. The handler will attempt to
* resolve them whenever new devices are discovered, by calling the parser's
* resolve_resource function. Once a boot option's resources are full resolved,
* the option can be sent to clients.
