WiX Extension

Tracking rimas-kudelis/windows-keyboard-layouts#1 (comment):

so I booted to Windows and used burn.exe from WiX toolset to decompile the MSI file. What it creates from it is a source WXS file and a single DLL binary containing custom actions for the installer. The custom actions that it provides are:

1. RegisterKeyboard (entrypoint CA01)
2. UnregisterKeyboard (entrypoint CA02)
3. AddKeyboardToLangBar (entrypoint CA03)
4. RemoveKeyboardFromLangBar (entrypoint CA04)

So the only thing that currently prevents us from having a completely open-source MSI version of that MSKLC-generated installer is this DLL.

With this extension at hand, proper per-platform (and maybe even cross-platform, if MSI allows that) MSI files could be generated.
