+Entrypoint for calling Evennia as a module, with
+
+    python -m evennia  (linux/unix)
+    py -m evennia  (windows)
+
+Notably, this should work also if evennia is installed with pip but
+the executable is not on the path (so the plain `evennia` command
+doesn't work).
+
+For windows, this will try to inject the evennia launcher into the executable path
+to make the `evennia` command available.
