-The server and the OBS script are written for Python 3.6, since at the time of writing, [OBS only supports 3.6](https://obsproject.com/wiki/Getting-Started-With-OBS-Scripting) for scripts. The source module for the built-in HTTP server from 3.9 is included in this project, since the 3.6 module does not allow for setting a custom server root (this feature was [introduced in 3.7](https://docs.python.org/3/library/http.server.html#http.server.SimpleHTTPRequestHandler)). If you are not using the OBS script (or if you don't mind dealing with multiple versions of Python on the same system), the daemon should work fine on 3.9 in theory, but this is not fully tested. When OBS eventually provides support for >=3.7, this package will be updated to use the native HTTP server module, and support for pre-3.7 will be dropped.\r
