Document Classes
================

   Valid LaTeX document classes include:

   * article

   * report

   * letter

   * book

   * slides

   Other document classes are often available. Note: Overview, for
details.  They are selected with the following command:

   `\documentclass [options] {class}'

   All the standard classes (except slides) accept the following options
for selecting the typeface size (10 pt is default):

   10pt, 11pt, 12pt

   All classes accept these options for selecting the paper size
(default is letter):

   a4paper, a5paper, b5paper, letterpaper, legalpaper, executivepaper

   Miscellaneous options:

   * landscape -- selects landscape format. Default is portrait.

   * titlepage, notitlepage -- selects if there should be a separate
     title page.

   * leqno -- equation number on left side of equations. Default is
     right side.

   * fleqn -- displayed formulas flush left. Default is centred.

   * openbib -- use "open" bibliography format.

   * draft, final -- mark/do not mark overfull boxes with a rule.
     Default is final.

   These options are not available with the slides class:

   * oneside, twoside -- selects one- or twosided layout. Default is
     oneside, except for the book class.

   * openright, openany -- determines if a chapter should start on a
     right-hand page. Default is openright for book.

   * onecolumn, twocolumn -- one or two columns. Defaults to one column.

   The slides class offers the option `clock' for printing the time at
the bottom of each note.

   If you specify more than one option, they must be separated by a
comma.

   Additional packages are loaded by a

   `\usepackage[options]{pkg}'

   command. If you specify more than one package, they must be
separated by a comma.

   Any options given in the `\documentclass' command that are unknown
by the selected document class are passed on to the packages loaded with
`\usepackage'.
