                    throws IOException

  Write contents of Map map to the File file. Output is written with one key, value pair on each line, in the format: key=value. Write to a temp file in the same directory and then rename, to not corrupt simultaneous accesses by the router. Except on Windows where renameTo() will fail if the target exists.

  Parameters:

  map - A Map to write to file.

  file - A File to write the Map to.

  Throws:

  IOException - if file cannot be written to.
