### 2 Typographic Conventions

The following typographic conventions are used in this cookbook.

Anything that is to be typed into a computer program via the keyboard,
or output from one via the screen, is indicated by a ‘typewriter’ font
like this.

Lines that are to be typed into the computer are shown beginning with a % sign, for example:

% gaia

The % indicates the Unix ‘shell prompt’ and should not be typed in. However:

items appearing in GAIA’s graphical windows are shown in a sans serif font like this.
