KAG System (Kirikiri Adventure Game System) is an application script for

KAG has a simple tag-based mark-up language ("scenario file").
Version under 2.x of KAG is slow since the parser is written in TJS1.
KAG 3.x uses TVP's internal KAG parser written in C++ in this unit, will
acquire speed in compensation for ability of customizing.
