`@pagesizes' [WIDTH][, HEIGHT]: Custom page sizes
=================================================
You can explicitly specify the height and (optionally) width of the
main text area on the page with the `@pagesizes' command. Write this
on a line by itself near the beginning of the Texinfo file, before the
title page. The height comes first, then the width if desired,
separated by a comma. Examples:
@pagesizes 200mm,150mm
and
@pagesizes 11.5in
This would be reasonable for printing on B5-size paper. To emphasize,
this command specifies the size of the _text area_, not the size of the
paper (which is 250mm by 177mm for B5, 14in by 8.5in for legal).
To make more elaborate changes, such as changing any of the page
margins, you must define a new command in `texinfo.tex' (or
`texinfo.cnf', Note:Preparing for TeX.).
Note:Format with texi2dvi, and Note:Preparing for TeX,
for other ways to specify `@pagesizes' that do not require
changing the source file.
`@pagesizes' is ignored by `makeinfo'.
