Conventions
In order to improve the readability of the manual, a menu-style breakdown was
used, i.e.:
• The individual chapters can be quickly located by means of a thumb register.
• There is an overview containing the headings of the individual chapters at the
beginning of the manual.
• Each chapter is preceeded by a breakdown of its subject matter.
The individual chapters are subdivided into sections and subsections. Bold
face type is used for further subdivisions.
• Pages, figures and tables are numbered separately in each chapter. The page
following the chapter breakdown contains a list of the figures and tables
appearing in that particular chapter.
Certain conventions were observed when writing the manual. These are
explained below.
• A number of abbreviations have been used.
Example: Central processing unit (CPU)
• Cross-references are shown as follows:
"( 7.3.2)" refers to subsection 7.3.2.
No references are made to individual pages.
