The commands without arguments always span some portion of the document, so we call them span commands . They may be nested, but may not overlap. There are two forms of span commands, style commands and format commands . The style commands mark some section of the text, typically a short sequence of text, with a single attribute, which may be either a semantic tag like important , or a formatting style like italic . Style commands may be nested in a block command, but block commands should not be nested in style commands.
Markup commands with arguments always take a single line.
These lines are added automatically by TIM as needed. This allows a file to define both a stand-alone document, and to be included as a section in some larger document. It takes two arguments, the name of the file, and a caption for the picture. The caption may be omitted. TIM Tools ILU provides a program called tim to turn TIM files into either PostScript, text, or GNU Info files.
