+# SSSWTool
+A tool utilizing [SelenScript](https://github.com/Avril112113/selenscript)'s parser to combine your StormWorks addon code into a single file.  
+The catch, it's intelligent and adds more features!  
+
+This project is currently **VERY work in progress**, it's lacking a decent CLI and various features.  
+As it is right now, it's not considered a replacement for other tools until further testing and features has been finished.  
+
+To clarify, the following is what this tool provides:
+- Combining multiple files into one.
+- Optional tracing with `--trace` which provides full stack traces at runtime with source file, line and column info
+- TODO: Config file (for predefined options and output path, eg)
+- TODO: Build output path.
+- TODO: Custom build actions.
+- TODO: vscode task template.
+
+## Usage
+Run `ssswtool.bat` either directly or `ssswtool` if it's on your PATH.  
+The file `script.lua` is the entrypoint, any files `require()` from there will be directly included into the output.  
+Build with `ssswtool build ./`, or with tracing `ssswtool build ./ --trace`  
+The default output directory is `<ADDON_SRC>/_build/script.lua` (not configurable yet)  
+
+## [Releases](https://github.com/Avril112113/SSSWTool/releases)
+See the [releases](https://github.com/Avril112113/SSSWTool/releases) for download.  
+If you want to use `ssswtool` anywhere, consider adding the `./SSSWTool/` to your PATH (the directory containing `ssswtool.bat`).  
+See (usage)[#Usage] for how to use this tool.  
+
+**Pre-Built Binaries:**  
+The releases come with `luajit` pre-built, you can delete the files and it'll use your system version instead.  
+SelenScript also comes with pre-built libraries for `lfs` and `lpeglabel` in `./SelenScript/libs`.
