What Does YSI Stand For?

No-one actually knows! The original idea was "Y_Less' Server Includes", but "Script" and "Server" were frequently intermixed, and there are more devs than just Y_Less now, so the "Y" just became a recursive acronym for "YSI". There are now several official meanings, each incorporating different aspects of YSI:

YSI Script Includes

Core libraries.

YSI Scripting Improvements

Coding libraries (pawn language extensions).

YSI Server Includes

Game related stuff (commands, properties, text etc).

YSI Script Incidentals

Extras, like login and commands.

YSI Seriously Incomprehensible

The macros (though in their defense, writing macros to do the parsing within the compiler limitations is VERY hard).

YSI Stupid Includes

y_tho.
