5: tags. Each \textbf{foil} tag can contain:
6:
7: \begin{itemize}
8: \item \textbf{image}\index{image}: required. The delimited text should
9: correspond to a published image resource. Example: \texttt{<image>/res/adm/includes/templates/man1.jpg</image>}.
10: The following image formats are recommended - gif, jpg or png. Other formats may work, but there may be printing or display issues.
11: The image should only appear once per foil.
12: \item \textbf{rectangle}\index{rectangle}: required. The delimited text
13: specifies a rectangular area that is correct, specified as \texttt{(x1,y1)-(x2,y2)},
14: where x1, x2, y1, and y2 are number corresponding to the x and y coordinates
15: of two corners that define a rectangle which specifies where the right
16: answer for this foil is located on the image. For example, \texttt{(0,0)-(100,200)}
17: will specify that a rectangle 100 pixels wide and 200 pixels tall,
18: situated in the upper left of the image, is correct. At least one
19: rectangle is required; multiple rectangles may be specified.
20: \item \textbf{text}\index{text}: required. The delimited text is printed
