+# Porting
+The backend relies on unix fifos so that client-instances of itself can talk to the main server instance. This may or may not
+be a total pain under Windows. I haven't tried it. It will probably be necessary to adjust the IO code, or to implement
+some alternate transport under Windows. If nothing else, there are paths that need to be adjusted, and there is a call to mkfifo
+which needs to be replaced with whatever mechanism it is under windows that creates named pipes or some  other equivalent construct.

+Chromium has partial compatibility with Firefox, so porting to Chromium might be doable, and probably easier than porting OS.
