<\body> uses the tag in order to specify global data for the document. These data are treated in two stages by the macro. , the document data are separated into several categories, according to whether the data should be rendered as a part of the main title or in footnotes or the abstract. , the data in each category are rendered using suitable macros. Each child of the is a tag with some specific information about the document. Currently implemented tags are , , , , , , , and . The tag may occur several times and is used in order to specify data for each of the authors of the document. Each child of the tag is a tag with information about the corresponding author. Currently implemented tags with author information are , , , and . Most of the tags listed above also correspond to macros for rendering the corresponding information as part of the main title. For instance, if the date should appear in bold italic at a distance of at least from the other title fields, then you may redefine as <\tm-fragment> <\inactive*> >>>>> The macro is used in order to make the text span appropriately over the width of the title. The and are special in the sense that they also render possible references to footnotes. For this reason, you should rather customize the and macros in order to customize the rendering of the title and the name themselves. Notice also that the and macros do not render anything, but rather call the and call-backs for setting the appropriate global page headers and footers. By default, the running title and author are extracted from the usual title and author names. In addition to the rendering macros which are present in the document, the main title (including author information, the date, ) is rendered using the macro. The author information, as part of the main title, is rendered using or , depending on whether the document has one or more authors. Footnotes to the title or to one of the authors are rendered using . These footnote macros always expect a tag on input, because they may compress it into a horizontal concatenation. The first stage of processing the document data is more complex and the reader is invited to take a look at the of the macros which are involved in this process. It is also good to study the definitions of these macros in the . In order to indicate the way things work, we finish with an example on how the email address and homepage of an author can be rendered in a footnote instead of the main title: <\tm-fragment> <\inactive*> <\quasi> |author-name>> |author-address>> > |author-email>> |author-homepage>> |author-note|document|>> >>
