### 6.1.2 Comments

Comments are text in the scene file included to make the scene file easier to read or understand. They are ignored by the ray-tracer and are there for your information. There are two types of comments in POV-Ray.

Two slashes are used for single line comments. Anything on a line after a double slash (`//`) is ignored by the ray-tracer. For example:

     // This line is ignored

You can have scene file information on the line in front of the comment as in:

     object { FooBar } // this is an object

The other type of comment is used for multiple lines. It starts with "`/*`" and ends with "`*/`". Everything in-between is ignored. For example:

     /* These lines
        are ignored
        by the
        ray-tracer */

This can be useful if you want to temporarily remove elements from a scene file. `/*` ... `*/` comments can comment out lines containing other `//` comments and thus can be used to temporarily or permanently comment out parts of a scene. `/*` ... `*/` comments can be nested, the following is legal:

     /* This is a comment
     // This too
     /* This also */
     */

Use comments liberally and generously. Well used, they really improve the readability of scene files.
