-*******************
- DOCUMENTATION
-*******************
-Leslie Lamport in writing LaTeX assumed that authors would write
-complete .sty (.clo) files to implement the design decisions for their
-publications. However, the overwhelming majority of LaTeX publications use the
-standard styles supplied by Lamport. These implement a particular set of
-typographic conventions, which while consistent are not of universal validity,
-for instance many publishers and authors would like a full stop:
-`4. Introduction'
-rather than
-`4 Introduction'.
-
-This file modifies the standard classes so that other conventions can be
-more easily implemented. Careful use of the file will allow a greater
-variation in the appearance of LaTeX documents.
-
-0. Changes to section implementation.
-The file redefines the way LaTeX deals with negative indents for section
-headings, placing the number in the margin and the heading itself flush
-with the margin. With negative indents it sets starred section headings
-flush (as it does when \thesection is empty.
-Standard LaTeX indenting can be produced by typing
->> \let\ifind\iffalse
-This file's version can be reestablished by typing
->> \let\ifind\ifdim
-
-The file also changes the way LaTeX reacts to empty numbers when sections have
-non-negative indents, placing the heading where the number would go, rather
-than further indented (as in standard LaTeX).
-This effect can be removed by redefining an internal macro \@makesvsec (see
-below).
-
-The indents, pre- and postskips for section headings are placed in registers
-so that they are constant throughout a document and (just as the heading sizes)
-do not react to surrounding size changes. You can change this back to ordinary
-LaTeX behaviour by \def ing them as macros rather than setting the register
-values (in that case you should probably use \smaller\larger from
-SMALLER.STY for the \...size commands).
-
-WARNING LaTeX typesets headings that run on by manipulating \everypar. If you
-make local changes to the heading style of such a section inside braces or a
-group you must ensure that a non-empty paragraph occurs before the closing
-brace. Otherwise some strange effects may occur, because the \everypar tokens
-will be evaluated outside the group (this is a feature of LaTeX, not of
-SECTION.STY). If your group ends with an empty section of this type just
-follow it with \leavevmode or an explicit space: \ .
-
-A detailed description of the format of LaTeX sectioning commands is given
-below (in paragraph 9). This is partially taken from the file LATEX.TEX.
-We first list the macros for local control which you can use without knowing
-this structure.
-
-The file sets vertical distances that LaTeX expressed in terms of `em's and
-`ex's in equivalent `\baselineskip's, as `em' is a measure of the horizontal
-size of a font and `ex' is not a true measure of the full height of a line.
-Earlier vesions used `ex's.
-
-The original values are placed as comments.
-
-1. Sizing commands for Parts, Chapters and Titles etc
-These are set to \large or whatever
-
->> \chsize: Chapter, Part Heading (\LARGE\large)
->> \hdsize: Chapter, Part Title Text (\Huge\huge\LARGE)
->> \ttsize: Title of Document (\Huge\huge\LARGE)
->> \ausize: Author (\LARGE\Large)
->> \dasize: Date. (\Large\large)
->> \secsize: Section (\Large\large)
->> \subsize: Subsection (\large\normalsize)
- subsubsection and below use \normalsize
-
-2. Layout commands for headings.
->> \hdpos: Positioning of heading (\raggedright) (\centering \raggedleft)
- (see section 9);
->> counter hddpth (default 0)
- Maximum section level for \hdpos (chapters and parts ALWAYS use hdpos).
- To centre section headings and above:
- \let\hdpos\centering\setcounter{hddepth}{1}
->> \fpind: Indenting of first paragraph after \Part \Chapter
- and also to override setting via preskip for sections.
- \let to \@afterindenttrue to indent, \@afterindentfalse for flush,
- \relax: flush after \Part \Chapter, negative preskips; indented otherwise
- (LaTeX default behaviour).
-
-3. Fonts
->> \ttfnt: font for title entries.
->> \hdfnt: font for all other headings (Part, Chapter..subparagraph).
->> \fefnt: font for theorem headings and description labels (fe=feature).
->> \thfnt: font for theorem statements.
->> \pgfnt: font for page numbers.
->> \mkfnt: font for page headings (mk=mark).
->> \mkcse: case for page headings.
- These can also be used to add other initial commands such as spaces or
- symbols.
-
-4. Optional punctuation (standard|my preference)
- These marks are transferred via auxiliary files for tables of contents etc.
- They should be \def'd if their current value is to be transferred, and \let
- if the value in force when the file auxiliary is read should be used.
-
->> \hddot ({}|.) (after inline headings, theorems etc)
->> \cpdot (:|.) (in figure/table captions - also apears in list of figures.
->> \nmdot ({}|.) (after section numbers etc)
-
-If these are \let to a single letter they are not expanded in the
- .toc.. files. So to remove \cpdot from list of figures:
- \let\cpdot\relax\listoffigures\let\cpdot:
-
-5. Spacing parameters.
- The macros for chapters and parts have been altered so that all the
- vertical spacing commands are in a single macro in each case.
-
->> \part inserts initial vertical space directly (preceded by \hbox{} if it
- is to be immovable) and passes the space between Part n and title
- in \@tempskipa and the space below the heading in \@tempskipb.
->> Both \chapter and \chapter* call \@makechapterhead{chaptertitle}.
- This passes {chaptertitle} on to \@makeschapterhead together with the
- vertical spacing. Default setting is
- \def\@makechapterhead#1{\hbox{}\@makeschapterhead{#1}{50\p@}{20\p@}{40\p@}}
- \hbox{} makes first skip immovable,
- the first length is space above the heading,
- The second is the space between Chapter nn and the chapter title
- The third is the space below the heading.
- For both Part and Chapter the middle space is removed if either the
- section name or title are missing.
- If both are missing, the first space is also removed
-
->> For sections and below the spaces are kept in registers:
- \secpreskp and \secpsrskp \secindent used for \section
- \subpreskp and \subpstskp \subindent used for \subsection/\subsubsection
- \paragraph uses \subindent \subpreskp \parpstskp
- \subparagraph uses \parindent \subpreskp \parpstskp
-
->> \secindent \subindent Heading indentation
->> \secpreskp \subpreskp Space before
->> \secpstskp \subpstskp \parpstskp Space after.
-
-6. Internal modifications
-
- Sections with negative indents have heading flush with margin.
-
- If \thesection is \empty
- \let\thesection\empty or \def\thesection{}
- then section does not step the section counter.
- If the section produces empty output for a value then
- the section will start flush at the margin or \secindent if it is positive
- and there will be no \nmdot.
- It will produce (flush) page headings and a table of contents entry.
- Similarly if \thechapter or \thepart are defined to be empty they will
- suppress the heading line `Chapter..' and not step the counter.
- To restore standard LaTeX behaviour temporarily define \thesection to be
- \empty
- \def\thesection{\empty}
- In that case you can adjust post number spacing in the heading.
- \section[Heading]{\hskip-1em Heading}
- You can also redefine \@makesecdot see paragraph 7.
-
-WARNING \letting \thesection etc to an unexpandable token (like \relax) will
-cause strange effects under LaTeX because its value will not be expanded.
-
- \maketitle suppresses page headings (\thispagestyle{empty}) and only resets
- \@title etc locally. So place in a group if you want to preserve these for
- later reference (eg. in headers).
-
-7. New internal macros
- Place any modifications in the section REDEFINITIONS of the main code
-
-> \@secdot contains section number and \nmdot if the number is non-empty.
-> \@makesecdot{NAME} defines \@secdot.
- To make LaTeX step the section counter independently of the definition
- of \thesection and always print \nmdot:
- \def\@makesecdot#1{\refstepcounter{#1}%
- \edef\@secdot{\csname the#1\endcsname}}
- If you want \nmdot suppressed when \thesection produces no output:
- \def\@makesecdot#1{\refstepcounter{#1}%
- \edef\@secdot{\expandafter\@gobifnul\csname the#1\endcsname\nmdot}}
-> \@makesvsec{INDENT} defines the \@svsec macro used by LaTeX to typeset the
- section number.. Its parameter is the indent so that it can react
- differently to negative indents. (it does NOT make the indent).
- To obtain standard LaTeX behaviour:
- \def\@makesvsec#1{\def\@svsec{\@secdot\quad}}
- To make positioning commands apply to the heading ignoring the number:
- \def\@makesvsec#1{\def\@svsec{\llap{@secdot\quad}}}
- Do NOT forget the #1.
-> \@contmark{NAME}{LEVEL}{HEADING} makes contents line and sectionmark.
-
- Contents headlines are defined by
-> \@tocheadline
- This allows these lines to be adjusted similarly to the \@dottedtocline
- commands for other contents lines. The format of these is defined below (in
- paragraph 11).
->@tocpagenum#1 sets #1 flush right in \@tocheadline.
- Redefine (\let\@tocpagenum\@gobble) to remove page numbers.
- \def\l@part{\@tocheadline{0}{2.25em}{3em}{\let\@tocpagenum\@gobble
- \centering\large\bf}}
- Centres parts lines of contents but leaves chapters unchanged
- \def\l@part{\@tocheadline{0}{2.25em}{3em}{\let\@tocpagenum\@gobble
- \centering\def\numberline##1{\hskip-\secindent
- \hbox to\secindent{##1\hfil}}\large\bf}}
- Same but centring ignores part number.
- \def\l@part{\@tocheadline{0}{2.25em}{3em}{\let\@tocpagenum\@gobble
- \centering\def\numberline##1{\hfilneg
- \hbox to\z@{##1\hss}\hfil}\large\bf}}
- Centres heading with number flush left
- Contents lines use \secindent as a temporary register
-
->\makeheading (set to \section*, \chapter*)
- Makes headings for contents, index etc.
- To put Contents itself in the contents list, redefine (locally):
- \let\thesection\empty\let\makeheading\section
-
-8. Additional macros
-> \@ifempty{test}{yes}{no} like \@ifundefined but tests for empty
- (fails iff test starts with ~ of catcode 12 (other) ).
-> \@gobifnul{a}{b} = \@ifempty{a}{}{ab}.
-
-9. Description of sectioning values
-
- \@startsection {NAME}{LEVEL}{INDENT}{PRESKIP}{POSTSKIP}{STYLE}
- optional * [ALTHEADING]{HEADING}
- Generic command to start a section.
-
- NAME : e.g., 'subsection' must be the name of a section counter
- LEVEL : a number, denoting depth of section -- section=1;
- number increases down the hierarchy.
- INDENT : Indentation of heading from left margin
- PRESKIP : Absolute value = skip to leave above the heading.
- If negative, then paragraph indent of text following
- heading is suppressed.
- POSTSKIP : if positive, then skip to leave below heading, else
- negative of skip to leave to right of run-on heading.
- ALTHEADING : for page headings and contents.
- STYLE : commands to set style
- If '*' missing, then increments the counter. If it is present, then
- there should be no [ALTHEADING] argument.
- Uses the counter 'secnumdepth' whose value is the highest section
- level that is to be numbered and entered into \@dottedtocline.
-
-10. Treatment of Section Entries
-
- NAME (fixed) Determines the counter to use.
-
- LEVEL (fixed) If level is greater than \counter{secnumdepth} (default 2) no
- indexentry or number
-
- INDENTS: \secindent (sections), \subindent (subsections,...,paragraphs).
- Subparagraphs have \parindent fixed. These are dimensions.
-
- Recommended: +-\parindent or 0pt
-
- If indent is negative then SECTION.STY causes the section number to be set
- flush right that distance from margin. Heading or text follows at the margin
- itself.
-
- Unnumbered headings are set at the margin if indent is negative. If the
- indent is non-negative they are set flush left with the number position.
-
- PRESKIPS \secpreskp (sections), \subpreskp(subsections..subparagraphs)
- POSTSKIPS \secpstskp (sections),\subpstskp(subsections,subsubsections)
- \parpstskp (paragraphs,subparagraphs)
-
- Recommended: leave PRESKIPS' abs values unchanged, They are set -ve to
- have flush first paragraphs. Use \secpreskp-\secpreskp to indent them.
- Recommended: set POSTSKIPS to -1em or -\parindent to make sections run on.
-
- By assigning these values to registers SECTION.STY makes them independent of
- the surrounding font and size. Set the registers if you want this, redefine
- them as macros if you want them to be font and size dependent.
-
- STYLE \secsize \subsize \hdfnt size and fonts.
- \secsize for sections,
- \subsize for subsections.
- Subsubsections and below have \normalsize (fixed).
- \hdfnt is universal for all headings.
-
-11. Contents entries.
-
- \@tocheadline{LEVEL}{PRESKIP}{INDENT}{STYLE}{ENTRY}{PAGENUM}
- \@dottedtocline{LEVEL}{MARGIN}{INDENT}{ENTRY}{PAGENUM}
-
- LEVEL : determines if entry made.
- PRESKIP : vertical gap above.
- INDENT : This must leave enough room for the chapter or section number
- : It is added to the margin for the next level.
- MARGIN : Left margin inherited from level above (zero for headlines).
- STYLE : Font sizing and setting.
-
- LaTeX assumes that the ENTRY for sections be defined by a macro \l@section.
- These are defined in the standard document styles but can be changed.
- All entries of the \l@section commands are fixed. SECTION.STY does not
- change the commands using \@dottedtocline in the style file. Those that do
- not do so (\l@part, \l@chapter) are modified to use \@tocheadline.
-
- INDENT for sections in {article} and chapters in {report} is rather tight at
- 1.5em. If you increase it should also increase the MARGINS for lower
- sections.
-
-12. The following internal LaTeX macros are redefined:
-
- \part\@part\@spart\@endpart
- \@chapter\@schapter (also \fi moved)
- \@makechapterhead functions of these have been significantly
- \@makeschapterhead changed.
-
- \ps@headings\ps@myheadings
- \section\subsection
- \subsubsection\paragraph
- \subparagraph
- \thebibliography
- \theindex
- \@begintheorem
- \@oparbegintheorem
- \@makecaption optional style features added
- \@startsection \fpind and does not pass #4 to \@sect,\@ssect
- \@sect,\@ssect ignored parameter removed
- \llap \@secdot used to adjust spacing
- if \p@section defined used for number style.
- calls \@makesecdot
- \@sect only: \@makesvsec and
- \@contmark, which is moved in
- \@svsechd so that \unskip in \@xsect works).
- \maketitle\@maketitle suppress page number, reset \@title.. locally
- \numberline adds space after number, so overfull box if
- too close to heading.
-
-CHANGES
- Ver 1.3 (3.Apr 98)
- If \secindent < 0, then \section* produces a flush heading, not outdented.
- \hdpos takes level as parameter and is used for all sections, not just
- \part and \chapter.
- `ex' measurements replaced by \baselineskip equivalents.
- Ver 1.31
- Bugfix: \relax added to \@alph, \@Alph to enable use with \@ifempty test.
- Ver 1.32
- Bugfixes: \hdpos added to \@ssect, unused macro \secpos removed,
- \nobreak added after \thechapter in \makechapterhead
- Ver 1.4
- \hdpos made simple macro again. Counter \hddepth determines when it
- should be used. Functions of \@makechapterhead, \@smakechapterhead

- \part calls \@spart which finishes off the heading.
- Memory use < 200 words.
-End of SECTION.STY \ No newline at end of file
