<\body> The physical lines in a document are broken into pages in a way similar to how paragraphs are hyphenated into lines. The page breaker performs , it tries to distribute page items evenly so text runs to the bottom of every page. It also tries to avoid , which are single or pairs of soft lines separated from the rest of their paragraph by a page break, but these can be produced when there is no better solution. <\explain> <|explain> Prevent the occurrence of an automatic page break after the current line. Set an infinite page breaking penalty for the current line, similarly to . Forbidden page breaking points are overridden by ``new page'' and ``page break'' primitives. <\explain> <|explain> Similar to , but set the page breaking penalty of the previous line. <\explain> <|explain> Cause the next line to appear on a new page, without filling the current page. The page breaker will not try to position the current line at the bottom of the page. <\explain> <|explain> Similar to , but start the new page before the current line. This directive is appropriate to use in chapter headings. <\explain> <|explain> Force a page break after the current line. A forced page break is different from a new page, the page breaker will try to position the current line at the bottom of the page. Use only to fine-tune the automatic page breaking. Ideally, this should be a hint similar to , but this is implemented as a directive, use only with extreme caution. <\explain> <|explain> Similar to , but force a page break before the current line. When several ``new page'' and ``page break'' directives apply to the same point in the document, only the first one is effective. Any or after the first one in a line is ignored. Any or in a line overrides any or in the following line. Any or after the first one in a line is ignored.
