-It's often necessary to typeset part of a document in landscape
-orientation; to achieve this, one needs not only to change the page
-dimensions, but also to instruct the output device to print the
-strange page differently.
-There are two "ordinary" mechanisms for doing two slight variations
-of landscape typesetting:
--  If you have a single floating object that is wider than it is
-    deep, and will only fit on the page in landscape orientation, use
-    the [`rotating`](https://ctan.org/pkg/rotating) package; this defines
-    `sidewaysfigure` and `sidewaystable`
-    environments which create floats that occupy a whole page.
-    Note that [`rotating`](https://ctan.org/pkg/rotating) has problems in a document that also
-    loads the [`float`](https://ctan.org/pkg/float) package, which recommended in other
-    answers in these FAQs, for example that on
-    [float placement](FAQ-floats).  The [`rotfloat`](https://ctan.org/pkg/rotfloat) package
-    loads [`rotating`](https://ctan.org/pkg/rotating) for you, and smooths the interaction with
-    [`float`](https://ctan.org/pkg/float).
--  If you have a long sequence of things that need to be typeset in
-    landscape (perhaps a code listing, a wide `tabbing`
-    environment, or a huge table typeset using [`longtable`](https://ctan.org/pkg/longtable) or
-    [`supertabular`](https://ctan.org/pkg/supertabular)), use the [`lscape`](https://ctan.org/pkg/lscape) package (or
-    [`pdflscape`](https://ctan.org/pkg/pdflscape) if you're generating PDF output, whether
-    using pdfLaTeX or `dvips` and generating PDF from
-    that).  Both packages define an environment `landscape`, which
-    clears the current page and restarts typesetting in landscape
-    orientation (and clears the page at the end of the environment
-    before returning to portrait orientation).
-No currently available package makes direct provision for typesetting
-in both portrait and landscape orientation on the same page (it's not
-the sort of thing that TeX is well set-up to do).  If such
-behaviour was an absolute necessity, one might use the techniques
-described in
-["flowing text around figures"](FAQ-textflow), and would
-rotate the landscape portion using the rotation facilities of the
-[`graphics`](https://ctan.org/pkg/graphics) package.  (Returning from landscape to portrait
-orientation would be somewhat easier: the portrait part of the page
-would be a bottom float at the end of the landscape section, with its
-content rotated.)
-To set an entire document in landscape orientation, one might use
-[`lscape`](https://ctan.org/pkg/lscape) around the whole document.  A better option is the
-`landscape` option of the [`geometry`](https://ctan.org/pkg/geometry) package; if you
-also give it `dvips` or `pdftex` option,
-[`geometry`](https://ctan.org/pkg/geometry) also emits the rotation instructions to cause the
-output to be properly oriented.  The [`memoir`](https://ctan.org/pkg/memoir) class has the same
-facilities, in this respect, as does [`geometry`](https://ctan.org/pkg/geometry).
-A word of warning: most current TeX previewers do not honour
-rotation requests in DVI files.
-Your best bet is to convert your output to PostScript or to PDF, and
-to view these "final" forms with an appropriate viewer.
