+Le format APT
+~~~~~~~~~~~~~
+
+ Dans la section suivante, les bo?tes contenant du texte dans la police
+ de type machine ? ?crire sont des exemples de source APT.
+
+* Structure du document
+~~~~~~~~~~~~~~~~~~~~~~~
+
+ A short APT document is contained in a single text file. A longer document
+ may be contained in a ordered list of text files. For instance, first text
+ file contains section 1, second text file contains section 2, and so on.
+
+ [Note:] Splitting the APT document in several text files on a section
+ boundary is not mandatory. The split may occur anywhere.
+ However doing so is recommended because a text file containing a
+ section is by itself a valid APT document.
+
+ A file contains a sequence of paragraphs and ``displays'' (non paragraphs
+ such as tables) separated by open lines.
+
+ A paragraph is simply a sequence of consecutive text lines.
+
++------------------------------------------------------------------------+
+ First line of first paragraph.
+ Second line of first paragraph.
+ Third line of first paragraph.
+
+ Line 1 of paragraph 2 (separated from first paragraph by an open line).
+ Line 2 of paragraph 2.
++------------------------------------------------------------------------+
+
+ The indentation of the first line of a paragraph is the main method used by
+ an APT processor to recognize the type of the paragraph. For example, a
+ section title must not be indented at all.
+
+ A ``plain'' paragraph must be indented by a certain amount of space. For
+ example, a plain paragraph which is not contained in a list may be indented
+ by two spaces.
+
++-------------------------------------------------+
+My section title (not indented).
+
+ My paragraph first line (indented by 2 spaces).
++-------------------------------------------------+
+
+ Indentation is not rigid. Any amount of space will do. You don't even need
+ to use a consistent indentation all over your document. What really matters
+ for an APT processor is whether the paragraph is not indented at all or,
+ when inside a list, whether a paragraph is more or less indented than the
+ first item of the list (more about this later).
+
++-------------------------------------------------------+
+ First paragraph has its first line indented by four
+spaces. Then the author did even bother to indent the
+other lines of the paragraph.
+
+ Second paragraph contains several lines which are all
+ indented by two spaces. This style is much nicer than
+ the one used for the previous paragraph.
++-------------------------------------------------------+
+
+ Note that tabs are expanded with a tab width set to 8.
+
+* Document elements
+~~~~~~~~~~~~~~~~~~~
+
+** Block level elements
+~~~~~~~~~~~~~~~~~~~~~~~
+
+*** Title
+~~~~~~~~~~
+
+ A title is optional. If used, it must appear as the first block of the
+ document.
+
++----------------------------------------------------------------------------+
+ ------
+ Title
+ ------
+ Author
+ ------
+ Date
++----------------------------------------------------------------------------+
+
+ A title block is indented (centering it is nicer). It begins with a line
+ containing at least 3 dashes (<<<--->>>).
+
+ After the first <<<--->>> line, one or several consecutive lines of text
+ (implicit line break after each line) specify the title of the document.
+
+ This text may immediately be followed by another <<<--->>> line and one or
+ several consecutive lines of text which specifies the author of the
+ document.
+
+ The author sub-block may optionaly be followed by a date sub-block using the
+ same syntax.
+
+ The following example is used for a document with an title and a date but
+ with no declared author.
+
++----------------------------------------------------------------------------+
+ ------
+ Title
+ ------
+ ------
+ Date
+ ------
++----------------------------------------------------------------------------+
+
+ The last line is ignored. It is just there to make the block nicer.
+
+*** Paragraph
+~~~~~~~~~~~~~
+
+ Paragraphs other than the title block may appear before the first section.
+
++----------------------+
+ Paragraph 1, line 1.
+ Paragraph 1, line 2.
+
+ Paragraph 2, line 1.
+ Paragraph 2, line 2.
++----------------------+
+
+ Paragraphs are indented. They have already been described in the {{document
+ structure}} section.
+
+*** Section
+~~~~~~~~~~~
+
+ Sections are created by inserting section titles into the document. Simple
+ documents need not contain sections.
+
++-----------------------------------+
+Section title
+
+* Sub-section title
+
+** Sub-sub-section title
+
+*** Sub-sub-sub-section title
+
+**** Sub-sub-sub-sub-section title
++-----------------------------------+
+
+ Section titles are not indented. A sub-section title begins with one
+ asterisk (<<<*>>>), a sub-sub-section title begins with two asterisks
+ (<<<**>>>), and so forth up to four sub-section levels.
+
+*** List
+~~~~~~~~
+
++---------------------------------------+
+ * List item 1.
+
+ * List item 2.
+
+ Paragraph contained in list item 2.
+
+ * Sub-list item 1.
+
+ * Sub-list item 2.
+
+ * List item 3.
++---------------------------------------+
+
+ List items are indented and begin with a asterisk (<<<*>>>).
+
+ Plain paragraphs more indented than the first list item are nested in that
+ list. Displays such as tables (not indented) are always nested in the
+ current list.
+
+ To nest a list inside a list, indent its first item more than its parent
+ list. To end a list, add a paragraph or list item less indented than the
+ current list.
+
+ Section titles always end a list. Displays cannot end a list but the
+ <<<[]>>> pseudo-element may be used to force the end of a list.
+
++------------------------------------+
+ * List item 3.
+ Force end of list:
+
+ []
+
+--------------------------------------------
+Verbatim text not contained in list item 3
+--------------------------------------------
++------------------------------------+
+
+ In the previous example, without the <<<[]>>>, the verbatim text (not
+ indented as all displays) would have been contained in list item 3.
+
+ A single <<<[]>>> may be used to end several nested lists at the same
+ time. The indentation of <<<[]>>> may be used to specify exactly which
+ lists should be ended. Example:
+
++------------------------------------+
+ * List item 1.
+
+ * List item 2.
+
+ * Sub-list item 1.
+
+ * Sub-list item 2.
+
+ []
+
+-------------------------------------------------------------------
+Verbatim text contained in list item 2, but not in sub-list item 2
+-------------------------------------------------------------------
++------------------------------------+
+
+ There are three kind of lists, the bulleted lists we have already described,
+ the numbered lists and the definition lists.
+
++-----------------------------------------+
+ [[1]] Numbered item 1.
+
+ [[A]] Numbered item A.
+
+ [[B]] Numbered item B.
+
+ [[2]] Numbered item 2.
++-----------------------------------------+
+
+ A numbered list item begins with a label beetween two square brackets. The
+ label of the first item establishes the numbering scheme for the whole list:
+
+ [<<<[[1\]\]>>>] Decimal numbering: 1, 2, 3, 4, etc.
+
+ [<<<[[a\]\]>>>] Lower-alpha numbering: a, b, c, d, etc.
+
+ [<<<[[A\]\]>>>] Upper-alpha numbering: A, B, C, D, etc.
+
+ [<<<[[i\]\]>>>] Lower-roman numbering: i, ii, iii, iv, etc.
+
+ [<<<[[I\]\]>>>] Upper-roman numbering: I, II, III, IV, etc.
+
+ The labels of the items other than the first one are ignored. It is
+ recommended to take the time to type the correct label for each item in
+ order to keep the APT source document readable.
+
++-------------------------------------------+
+ [Defined term 1] of definition list 2.
+
+ [Defined term 2] of definition list 2.
++-------------------------------------------+
+
+ A definition list item begins with a defined term: text between square
+ brackets.
+
+*** Verbatim text
+~~~~~~~~~~~~~~~~~
+
++----------------------------------------+
+----------------------------------------
+Verbatim
+ text,
+ preformatted,
+ escaped.
+----------------------------------------
++----------------------------------------+
+
+ A verbatim block is not indented. It begins with a non indented line
+ containing at least 3 dashes (<<<--->>>). It ends with a similar line.
+
+ <<<+-->>> instead of <<<--->>> draws a box around verbatim text.
+
+ Like in HTML, verbatim text is preformatted. Unlike HTML, verbatim text is
+ escaped: inside a verbatim display, markup is not interpreted by the APT
+ processor.
+
+*** Figure
+~~~~~~~~~~
+
++---------------------------+
+[Figure name] Figure caption
++---------------------------+
+
+ A figure block is not indented. It begins with the figure name between
+ square brackets. The figure name is optionally followed by some text: the
+ figure caption.
+
+ The figure name is the pathname of the file containing the figure but
+ without an extension. Example: if your figure is contained in
+ <<</home/joe/docs/mylogo.jpeg>>>, the figure name is
+ <<</home/joe/docs/mylogo>>>.
+
+ If the figure name comes from a relative pathname (recommended practice)
+ rather than from an absolute pathname, this relative pathname is taken to be
+ relative to the directory of the current APT document (a la HTML)
+ rather than relative to the current working directory.
+
+ Why not leave the file extension in the figure name? This is better
+ explained by an example. You need to convert an APT document to PostScript
+ and your figure name is <<</home/joe/docs/mylogo>>>. A APT processor will
+ first try to load <<</home/joe/docs/mylogo.eps>>>. When the desired format
+ is not found, a APT processor tries to convert one of the existing
+ formats. In our example, the APT processor tries to convert
+ <<</home/joe/docs/mylogo.jpeg>>> to encapsulated PostScript.
+
+*** Table
+~~~~~~~~~
+
+ A table block is not indented. It begins with a non indented line containing
+ an asterisk and at least 2 dashes (<<<*-->>>). It ends with a
+ similar line.
+
+ The first line is not only used to recognize a table but also to specify
+ column justification. In the following example,
+
+ * the second asterisk (<<<*>>>) is used to specify that column 1 is
+ centered,
+
+ * the plus sign (<<<+>>>) specifies that column 2 is left aligned,
+
+ * the colon (<<<:>>>) specifies that column 3 is right aligned.
+
+ []
+
++---------------------------------------------+
+*----------*--------------+----------------:
+| Centered | Left-aligned | Right-aligned |
+| cell 1,1 | cell 1,2 | cell 1,3 |
+*----------*--------------+----------------:
+| cell 2,1 | cell 2,2 | cell 2,3 |
+*----------*--------------+----------------:
+Table caption
++---------------------------------------------+
+
+ Rows are separated by a non indented line beginning with <<<*-->>>.
+
+ An optional table caption (non indented text) may immediately follow the
+ table.
+
+ Rows may contain single line or multiple line cells. Each line of cell text
+ is separated from the adjacent cell by the pipe character (<<<|>>>).
+ (<<<|>>> may be used in the cell text if quoted: <<<\\|>>>.)
+
+ The last <<<|>>> is only used to make the table nicer. The first <<<|>>> is
+ not only used to make the table nicer, but also to specify that a grid is to
+ be drawn around table cells.
+
+ The following example shows a simple table with no grid and no caption.
+
++---------------+
+*-----*------*
+ cell | cell
+*-----*------*
+ cell | cell
+*-----*------*
++---------------+
+
+*** Horizontal rule
+~~~~~~~~~~~~~~~~~~~
+
++---------------------+
+=====================
++---------------------+
+
+ A non indented line containing at least 3 equal signs (<<<===>>>).
+
+*** Page break
+~~~~~~~~~~~~~~
+
++---+
+^L
++---+
+
+ A non indented line containing a single form feed character (Control-L).
+
+** Text level elements
+~~~~~~~~~~~~~~~~~~~~~~
+
+*** Font
+~~~~~~~~
+
++-----------------------------------------------------+
+ <Italic> font. <<Bold>> font. <<<Monospaced>>> font.
++-----------------------------------------------------+
+
+ Text between \< and > must be rendered in italic. Text between \<\< and >>
+ must be rendered in bold. Text between \<\<\< and >>> must be rendered using
+ a monospaced, typewriter-like font.
+
+ Font elements may appear anywhere except inside other font elements.
+
+ It is not recommended to use font elements inside titles, section titles,
+ links and defined terms because a APT processor automatically applies
+ appropriate font styles to these elements.
+
+*** Anchor and link
+~~~~~~~~~~~~~~~~~~~
+
++-----------------------------------------------------------------+
+ {Anchor}. Link to {{anchor}}. Link to {{http://www.pixware.fr}}.
+ Link to {{{anchor}showing alternate text}}.
+ Link to {{{http://www.pixware.fr}Pixware home page}}.
++-----------------------------------------------------------------+
+
+ Text between curly braces (<<<\{}>>>) specifies an anchor. Text between
+ double curly braces (<<<\{\{}}>>>) specifies a link.
+
+ It is an error to create a link element that does not refer to an anchor of
+ the same name. The name of an anchor/link is its text with all non
+ alphanumeric characters stripped.
+
+ This rule does not apply to links to <external> anchors. Text beginning
+ with <<<http:/>>>, <<<https:/>>>, <<<ftp:/>>>, <<<file:/>>>, <<<mailto:>>>,
+ <<<../>>>, <<<./>>> (<<<..\\>>> and <<<.\\>>> on Windows) is recognized as
+ an external anchor name.
+
+ When the construct <<\{\{\{>><name><<}>><text><<}}>> is used, the link text
+ <text> may differ from the link name <name>.
+
+ Anchor/link elements may appear anywhere except inside other anchor/link
+ elements.
+
+ Section titles are implicitly defined anchors.
+
+*** Line break
+~~~~~~~~~~~~~~
+
++-------------+
+ Force line\
+ break.
++-------------+
+
+ A backslash character (<<<\\>>>) followed by a newline character.
+
+ Line breaks must not be used inside titles and tables (which are line
+ oriented blocks with implicit line breaks).
+
+*** Non breaking space
+~~~~~~~~~~~~~~~~~~~~~~
+
++----------------------+
+ Non\ breaking\ space.
++----------------------+
+
+ A backslash character (<<<\\>>>) followed by a space character.
+
+*** Special character
+~~~~~~~~~~~~~~~~~~~~~
+
++---------------------------------------------------------------------------+
+ Escaped special characters: \~, \=, \-, \+, \*, \[, \], \<, \>, \{, \}, \\.
++---------------------------------------------------------------------------+
+
+ In certain contexts, these characters have a special meaning and therefore
+ must be escaped if needed as is. They are escaped by adding a backslash in
+ front of them. The backslash may itself be escaped by adding another
+ backslash in front of it.
+
+ Note that an asterisk, for example, needs to be escaped only if its begins a
+ paragraph. (<<<*>>> has no special meaning in the middle of a paragraph.)
+
++--------------------------------------+
+ Copyright symbol: \251, \xA9, \u00a9.
++--------------------------------------+
+
+ Latin-1 characters (whatever is the encoding of the APT document) may be
+ specified by their codes using a backslash followed by one to three octal
+ digits or by using the <<<\x>>><NN> notation, where <NN> are two hexadecimal
+ digits.
+
+ Unicode characters may be specified by their codes using the <<<\u>>><NNNN>
+ notation, where <NNNN> are four hexadecimal digits.
+
+*** Comment
+~~~~~~~~~~~
+
++---------------+
+~~Commented out.
++---------------+
+
+ Text found after two tildes (<<<\~~>>>) is ignored up to the end of line.
+
+ A line of <<<~>>> is often used to ``underline'' section titles in order to
+ make them stand out of other paragraphs.
