- * \brief Debugging interfaces.
- *
- * This module provides functions to draw debugging information within the game
- * window. It is mostly used for information only when state of the game is
- * better inspected via direct window information rather than writing in the
- * console.
- *
- * Predefined core states may print debugging information if
- * debug_options.enabled variable is set to true. However, you need to specify
- * the font to use in order to work.
- *
- * Each call to \ref debugf or \ref vdebugf automatically adjust
- * next coordinate for rendering the text. As such, user may simply print
- * several lines of text without having to deal with that manually.
