Framework and / or libraries (all kind of mashed together) and some C++ bindings, used by the game Icebreakers.
The provenance of the name was a silly little discussion at the office. :) Trail Mix and Ice Sculptor (after the ice "trails") were also tossed around.
This is a continuation of some of the code already developed in a UI editor and some other projects, and then honed over time to meet the demands of a game. It was targeted against the Vision SDK, though the intent was to make it adaptable.
Lua 5.1 and LuaJIT were out (at least once the project got going), but we already had A LOT of non-module stuff which would have been painful to port, thus the "boot" files and associated loading scheme. Also, the GC often caught a case of the hiccoughs, so a lot of deep code ended up doing recycling, plus we threw in an arena allocator for good measure.
Game-specific code is omitted, for the most part. A hint of some menus and the localization scheme remain, and most (all?) of the boot files themselves. The vast majority of the C++ is elided too, since it's either game-specific as well or touches a lot of middleware.
