Conventions

There are a number of conventions used in this document. One set of conventions use the typeface to indicate what kind of object is being described. These conventions are

Bold
This is the name of a script, e.g. tnt.
Teletype
This is a file name, e.g. tnt/data/formfactor.dat. This typeface is also used to display exact dialogs between the user and the computer. In such an example the text typed by the user is in bold.

This is the name of a program, e.g. Rfactor.

Another series of conventions are involved in the specification of syntax. When describing a data statement or command there has to be a method to specify that something is optional or something else can be repeated. These conventions are

< ...>
Substitute a value. The text within the broken brackets describes the value. In the input line the broken brackets are not entered.
N( ...)
Repeat the contents of the parenthesizes zero or more times.

The contents of the brackets are optional.
{ ...| ...}
Choose one of the options separated by ``|". There may be more than two options to choose from.
