This is NOT a WoW addon, it is a tool for building and releasing WoW addons.
It is a development tool. This particular zip is uploaded to the three popular WoW Addon distribution platforms - Hello folks at curse!
It contains the Windows AMD64 binary within wow-build-tools_windows_amd64.zip.

For more information, see the GitHub repository which has releases for other platforms as well as a Wiki.

Also, the project is still in BETA, so please report any issues you find.
Thank you for reading this and for your interest in wow-build-tools :)
