Something in C. Something that did not rely on nested lists to represent a bitmap. Thus, the Gimp was born. 4 T h e G i m p Us er ’ s M a n u a l W ha t I shell.

GNU Image Manipulation Program Generated k 2 o d f Defining A List Before we talk more about lists, it is necessary that you know the difference between atomic values and lists. You've already seen atomic values when we initialized variables defined as such: '() ‚‚‚‚‚‚‚‚ ‚‚‚‚‚‚ or simply: () ‚‚‚‚‚‚‚‚ ‚‚‚‚‚‚ Lists can contain atomic values, as well as other lists: (let* ‚‚‚‚‚‚‚‚ GNU Image Manipulation Program Generated by docbook2odf
