A utility to compile & decompile IW engine game scripts.
## Supported Games 
- **IW5** *(Call of Duty: Modern Warfare 3)*
- **IW6** *(Call of Duty: Ghosts)*
- **IW7** *(Call of Duty: Infinite Warfare)*
- **IW8** *(Call of Duty: Modern Warfare (2019))*

## Usage
``./gsc-tool.exe <mode> <game> <path>``

**modes**: `asm`, `disasm`, `comp`, `decomp` 

**games**: `iw5`, `iw6`, `iw7`, `iw8`, `s1`, `s2`, `s4`, `h1`, `h2` 

**paths**: `file`, `directory` (recursive process all files with mode extension) 

for zonetool files (*.cgsc*, *.cgsc.stack*) use: `zasm`, `zdisasm`, `zcomp`, `zdecomp`

| Mode     |Description                | Output      |
|:---------|:--------------------------|:------------|
|`asm`     |assemble a `file.gscasm`   |`file.gscbin`|
|`disasm`  |dissasemble a `file.gscbin`|`file.gscasm`|
|`comp`    |compile a `file.gsc`       |`file.gscbin`|
|`decomp`  |decompile a `file.gscbin`  |`file.gsc`   |

## 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``.
