/**
 * @defgroup advanced_config Advanced Configuration Variables
 *
 * Class containing "advanced" configuration options.
 *
 * Options set here are for developer or advanced users only. If a general user
 * needs to set one of these for normal KiCad use, either:
 * * They are working around some bug that should be fixed, or
 * * The parameter they are setting is of general interest and should be in the
 *   main application config, with UI provided.
 *
 * Options in this class are, in general, preferable to #defines, as they
 * allow more flexible configuration by developers, and don't hide code from
 * the compiler on other configurations, which can result in broken builds.
 *
 * Never use advanced configs in an untestable way. If a function depends on
 * advanced config such that you cannot test it without changing the config,
 * "lift" the config to a higher level and make pass it as parameter of the code
 * under test. The tests can pass their own values as needed.
 *
 * This also applies to code that does not depend on "common" - it cannot
 * use this class, so you must pass configuration in as proper parameters.
 *
 * Sometimes you can just use values directly, and sometimes helper functions
 * might be provided to allow extra logic (for example when a advanced config
 * applies only on certain platforms).
 *
 * For more information on what config keys set these parameters in the
 * config files, and why you might want to set them, see #AC_KEYS
 *
