Help:Context

The <context> ... </context> tags process their ConTeXt contents on the fly and include the result on the page as an image. Whitespace is cropped out. The following options are available:

• source=yes displays the source before the output.
• text="some text" places 'some text' between the source and the output.
• mode=mkiv ensures Mark IV is used instead of the default Mark II.

For some reason, examples using the default A4 paper size usually end up blown up twice as large. If this happens, include \setuppapersize[A5] in your example, and everything will display at its proper size again. This has the added advantage that the resulting image will never be too large for this wiki's main column.

Displaying multiple pages

\setuppapersize[A10, landscape][A8, landscape]

\setuppaper[nx=2, ny=2]     % arrange pages 2 by 2 (must come before \setuparranging[XY])
\setuparranging[XY]         % arrange pages n by n (across, then down)
\setuppagenumbering[footer] % page numbers are always useful
\showframe[edge]            % Draw line around each page. Prevents overzealous cropping

one \page[yes]
two \page[yes]
three \page[yes]
four
