### Adding comment

You can add your comment to .rt files.

They use the C++ style:

1) you can put you comments from "/*" to "*/"

2) you can start comments from "//" until the end of line

For example:

/* RT example

more line, this is a comment

*/

{object

...

model { sphere // comment until the end of line

...

}

}

.

Remember that if you use with some automatic programs which work on .rt file you will lose these comments!
