## Format
- gsc-tool ``.gscbin`` format is a serialized ScriptFile struct: ***name***: null-term string, ***compressedLen***: 4 byte uint, ***len***: 4 byte uint, ***bytecodeLen***: 4 byte uint, ***buffer***: byte array[compressedLen], ***bytecode***: byte array[bytecodeLen].

- zonetool format made of bytecode file ``.cgsc`` and decompressed stack buffer ``.cgsc.stack``.
