"""Generate port/src/core/particles.h: gparticles, the precompiled Lua 5.0 chunk "particles.lua" (the particle
script helpers: CreateValue, CompileParameters, the Lua side of the particle language) that
TLuaParticleSystem::NewScript runs with lua_dobuffer(L, gparticles, 0x20d2, "particles.lua") when it creates a
script, copied byte for byte from the shipped game binary (__data @0x001d9700, symbol _gparticles, 0x20d2 bytes;
the size is the immediate of the lua_dobuffer call at game 0x0009b7e9).
