Twine is a authoring system by Chris Klimas that uses wiki technology to create CYOA stories into a single HTML/CSS page for playing. A Twine story can be non-trivial, that is, have a world state that changes in response to the player's choices. For example, the game can remember if the player-character acquired a silver key and not offer the choice to use it when the PC doesn't have it.
Twine story files have a .tws file extension; output files are saved with a .html extension.
Twine is also released with Twee, the command-line version of Twine. This allows Twine authors to use their own editors instead of Twine's interface, if they prefer.
