" The Cangjie programming language is a new-generation programming
" language oriented to full-scenario intelligence. It features
" native intelligence, being naturally suitable for all scenarios,
" high performance and strong security. It is mainly applied in
" scenarios such as native applications and service applications
" of HarmonyOS NEXT, providing developers with a good programming
" experience.
