Weird project description. Is it an X11 Server for Windows? If so, why doesn't it say this first (but only mentions further down that the software includes some advanced X11 Server)?
It includes binaries for VcXsrv[1], which is an X11 server for Windows. This project itself seems to be glue code that helps you set up and manage VcXsrv and it's connection with your WSL instances.
