Some hints

A .rt file is a little verbose. A good technique is to start form some already written files and to modify them, adding sections using copy and paste in a text editor.

A text file is slower to read than a binary file, but it is simple to edit and understand. It is more flexible.

Next versions or RT will improve the file format, adding new features or modifying olds, but old formats will be always compatible, so all you learn you can always use: the program will auto-translate old characteristics into new. Another bonus of text file format is that you can easily write a program which outputs a scene description in text file format, while it is complex to do in binary mode.
