XWadTools

XWadTools is a collection of wad editing tools, originally created for Unix-like systems but able to be compiled on other platforms.

The collection includes a WAD level compiler, ACS script compiler, graphics resources compiler, graphics extract utilities, node builders, tools to extract and import raw data into WAD files, and GUI map editor.

The archive includes source only and no binaries for any platform, so the package has to be compiled manually by the user.

The tools can be found here.
