@Section @Title { Introduction } @Begin @PP The Lout definitions for the @Code "@Fig" symbol are kept in a file called {@Code "fig"}, which you must include at the start of your document if fig.file @Index { @Code "fig" file } you want advanced graphics, like this: @ID @OneRow @Code { "@SysInclude { fig }" "@SysInclude { doc }" "@Doc @Text @Begin" "..." "@End @Text" } Files of definitions, like {@Code "fig"}, must be included before the setup file. Alternatively, if you are using your own setup file, you may place the include commands within it; the place to put them is clearly marked in all the standard setup files. @PP Throughout this chapter we will show the Lout text on the left and the corresponding result on the right, like this: @ID { @Code { "@Fig {" " @Square" " //0.5c" " @Circle" "}" } ||7ct @Fig { @Square //0.5c @Circle } } Subsequent examples will omit the enclosing {@Code "@Fig"}. @End @Section
