Environments ::begin::end::
############################################################

LaTeX provides a number of different paragraph-making 
environments. Each environment begins and ends in the same 
manner. 

 \begin{environment-name}
  .
  .
  .
 \end{environment-name}

	array: Math arrays. 
	center: Centred lines. 
	description: Labelled lists. 
	enumerate: Numbered lists. 
	eqnarray: Sequences of aligned equations. 
	equation: Displayed equation. 
	figure: Floating figures. 
	flushleft: Flushed left lines. 
	flushright: Flushed right lines. 
	itemize: Bulleted lists. 
	letter: Letters. 
	list: Generic list environment. 
	minipage: Miniature page. 
	picture: Picture with text, arrows, lines and 
		circles. 
	quotation: Indented environment with paragraph 
		indentation. 
	quote: Indented environment with no paragraph 
		indentation. 
	tabbing: Align text arbitrarily. 
	table: Floating tables. 
	tabular: Align text in columns. 
	thebibliography: Bibliography or reference list. 
	theorem: Theorems, lemmas, etc. 
	titlepage: For hand crafted title pages. 
	verbatim: Simulating typed input. 
	verse: For poetry and other things. 

############################################################
	array ::array::
############################################################

\begin{array}{col1col2...coln}
column 1 entry & column 2 entry ... & column n entry \\
 .
 .
 .
\end{array}

Math arrays are produced with the array environment. It has 
a single mandatory argument describing the number of columns 
and the alignment within them. Each column, coln, is specified 
by a single letter that tells how items in that row should 
be formatted. 

	c -- for centred 
	l -- for flush left 
	r -- for flush right 

Column entries must be separated by an &. Column entries may 
include other LaTeX commands. Each row of the array must be 
terminated with the string \\. 

Note that the array environment can only be used in math mode, 
so normally it is used inside an equation environment. 
############################################################
	center ::center::
############################################################

 \begin{center}
 Text on line 1 \\
 Text on line 2 \\
 .
 .
 .
 \end{center}

The center environment allows you to create a paragraph 
consisting of lines that are centred within the left and 
right margins on the current page. Each line must be 
terminated with the string \\. 

\centering: The declaration form of the center environment. 

############################################################
	\centering ::centering::
############################################################
This declaration corresponds to the center environment. This 
declaration can be used inside an environment such as quote 
or in a parbox. The text of a figure or table can be centred 
on the page by putting a \centering command at the beginning 
of the figure or table environment. 

Unlike the center environment, the \centering command does 
not start a new paragraph; it simply changes how LaTeX 
formats paragraph units. To affect a paragraph unit's format, 
the scope of the declaration must contain the blank line or 
\end command (of an environment like quote) that ends the 
paragraph unit. 
############################################################
	description ::discription::
############################################################

 \begin{description}
 \item [label] First item
 \item [label] Second item
 .
 .
 .
 \end{description}

The description environment is used to make labelled lists. 
The label is bold face and flushed right. 
############################################################
	enumerate ::enumerate::
############################################################

 \begin{enumerate}
 \item First item
 \item Second item
 .
 .
 .
 \end{enumerate}

The enumerate environment produces a numbered list. 
Enumerations can be nested within one another, up to four 
levels deep. They can also be nested within other 
paragraph-making environments. 

Each item of an enumerated list begins with an \item command. 
There must be at least one \item command within the environment. 
The enumerate environment uses the enumi through enumiv 
counters (see section Counters). The type of numbering can be 
changed by redefining \theenumi etc. 
############################################################
	eqnarray ::eqnarray::
############################################################

 \begin{eqnarray}
 math formula 1 \\
 math formula 2 \\
 .
 .
 .
 \end{eqnarray}

The eqnarray environment is used to display a sequence of 
equations or inequalities. It is very much like a three-column 
array environment, with consecutive rows separated by \\ and 
consecutive items within a row separated by an &.
 
An equation number is placed on every line unless that line 
has a \nonumber command. 

The command \lefteqn is used for splitting long formulas 
across lines. It typesets its argument in display style flush 
left in a box of zero width. 
############################################################
	equation ::equation::
############################################################

 \begin{equation}
  math formula
 \end{equation}

The equation environment centres your equation on the page 
and places the equation number in the right margin. 
############################################################
	figure ::figure::
############################################################

 \begin{figure}[placement]

  body of the figure

 \caption{figure title}
 \end{figure}

Figures are objects that are not part of the normal text, and 
are usually "floated" to a convenient place, like the top of 
a page. Figures will not be split between two pages.
 
The optional argument [placement] determines where LaTeX will 
try to place your figure. There are four places where LaTeX 
can possibly put a float: 
	h (Here) - at the position in the text where the 
		figure environment appears. 
	t (Top) - at the top of a text page. 
	b (Bottom) - at the bottom of a text page. 
	p (Page of floats) - on a separate float page, which 
		is a page containing no text, only floats. 
The standard report and article classes use the default 
placement tbp. 

The body of the figure is made up of whatever text, LaTeX 
commands, etc. you wish. The \caption command allows you to 
title your figure. 
############################################################
	flushleft ::flushleft::
############################################################

 \begin{flushleft}
 Text on line 1 \\
 Text on line 2 \\
 .
 .
 .
 \end{flushleft}

The flushleft environment allows you to create a paragraph 
consisting of lines that are flushed left, to the left-hand 
margin. Each line must be terminated 
with the string \\. 

	\raggedright: The declaration form of the flushleft 
		environment. 

############################################################
		\raggedright ::raggedright::
############################################################
This declaration corresponds to the flushleft environment. 
This declaration can be used inside an environment such as 
quote or in a parbox. 

Unlike the flushleft environment, the \raggedright command 
does not start a new paragraph; it simply changes how LaTeX 
formats paragraph units. To affect a paragraph unit's format, 
the scope of the declaration must contain the blank line or 
\end command (of an environment like quote) that ends the 
paragraph unit. 
############################################################
	flushright ::flushright::
############################################################

 \begin{flushright}
 Text on line 1 \\
 Text on line 2 \\
 .
 .
 .
 \end{flushright}

The flushright environment allows you to create a paragraph 
consisting of lines that are flushed right, to the right-hand 
margin. Each line must be terminated with the string \\.
 
	\raggedleft: The declaration form of the flushright environment. 

############################################################
		\raggedleft ::raggedleft::
############################################################
This declaration corresponds to the flushright environment. 
This declaration can be used inside an environment such as 
quote or in a parbox. 

Unlike the flushright environment, the \raggedleft command 
does not start a new paragraph; it simply changes how LaTeX 
formats paragraph units. To affect a paragraph unit's format, 
the scope of the declaration must contain the blank line or 
\end command (of an environment like quote) that ends the 
paragraph unit. 
############################################################
	itemize ::itemize::
############################################################

 \begin{itemize}
 \item First item
 \item Second item
 .
 .
 .
 \end{itemize}

The itemize environment produces a "bulleted" list. 
Itemizations can be nested within one another, up to four 
levels deep. They can also be nested within other 
paragraph-making environments. Each item of an itemized list 
begins with an \item command. There must be at least one 
\item command within the environment. The itemize environment 
uses the itemi through itemiv counters (see section Counters). 
The type of numbering can be changed by redefining \theitemi 
etc. 
############################################################
	letter ::letter::
############################################################
This environment is used for creating letters. See section 
Letters. 
############################################################
	list ::list::item::
############################################################
The list environment is a generic environment which is used 
for defining many of the more specific environments. It is 
seldom used in documents, but often in macros. 

 \begin{list}{label}{spacing}
 \item First item
 \item Second item
 .
 .
 .
 \end{list}

The {label} argument specifies how items should be labelled. 
This argument is a piece of text that is inserted in a box 
to form the label. This argument can and usually does contain 
other LaTeX commands. 

The {spacing} argument contains commands to change the spacing 
parameters for the list. This argument will most often be 
null, i.e., {}. This will select all default spacing which 
should suffice for most cases. 
############################################################
	minipage ::minipage::
############################################################

 \begin{minipage}[position]{width}
  text
 \end{minipage}

The minipage environment is similar to a \parbox command. It 
takes the same optional position argument and mandatory width 
argument. You may use other paragraph-making environments 
inside a minipage. Footnotes in a minipage environment are 
handled in a way that is particularly useful for putting 
footnotes in figures or tables. A \footnote or \footnotetext 
command puts the footnote at the bottom of the minipage 
instead of at the bottom of the page, and it uses the 
mpfootnote counter instead of the ordinary footnote counter 

See section Counters. 

NOTE: Don't put one minipage inside another if you are using 
footnotes; they may wind up at the bottom of the wrong 
minipage. 
############################################################
	picture ::picture::
############################################################
 \begin{picture}(width,height)(x offset,y offset)
  .
  .
  picture commands
  .
  .
 \end{picture}
The picture environment allows you to create just about any 
kind of picture you want containing text, lines, arrows and 
circles. You tell LaTeX where to put things in the picture 
by specifying their coordinates. A coordinate is a number 
that may have a decimal point and a minus sign -- a number 
like 5, 2.3 or -3.1416. A coordinate specifies a length in 
multiples of the unit length \unitlength, so if \unitlength 
has been set to 1cm, then the coordinate 2.54 specifies a 
length of 2.54 centimetres. You can change the value of 
\unitlength anywhere you want, using the \setlength command, 
but strange things will happen if you try changing it inside 
the picture environment. 

A position is a pair of coordinates, such as (2.4,-5), 
specifying the point with x-coordinate 2.4 and y-coordinate -5. 
Coordinates are specified in the usual way with respect to 
an origin, which is normally at the lower-left corner of the 
picture. Note that when a position appears as an argument, it 
is not enclosed in braces; the parentheses serve to delimit 
the argument. 

The picture environment has one mandatory argument, which is 
a position. It specifies the size of the picture. The 
environment produces a rectangular box with width and height 
determined by this argument's x- and y-coordinates. 

The picture environment also has an optional position argument, 
following the size argument, that can change the origin. 
(Unlike ordinary optional arguments, this argument is not 
contained in square brackets.) The optional argument gives the 
coordinates of the point at the lower-left corner of the picture 
(thereby determining the origin). For example, if \unitlength has 
been set to 1mm, the command
 
	\begin{picture}(100,200)(10,20)

produces a picture of width 100 millimetres and height 200 
millimetres, whose lower-left corner is the point (10,20) and 
whose upper-right corner is therefore the point (110,220). When 
you first draw a picture, you will omit the optional argument, 
leaving the origin at the lower-left corner. If you then want to 
modify your picture by shifting everything, you just add the 
appropriate optional argument. The environment's mandatory 
argument determines the nominal size of the picture. 

This need bear no relation to how large the picture really is; 
LaTeX will happily allow you to put things outside the picture, 
or even off the page. The picture's nominal size is used by LaTeX 
in determining how much room to leave for it. 

Everything that appears in a picture is drawn by the \put command. 
The command 

	\put (11.3,-.3){...}

puts the object specified by ... in the picture, with its reference 
point at coordinates (11.3,-.3). The reference points for various 
objects will be described below. The \put command creates an LR box. 
You can put anything in the text argument of the \put command that 
you'd put into the argument of an \mbox and related commands. When 
you do this, the reference point will be the lower left corner of 
the box. 

Picture commands: 

	\circle: Draw a circle. 
	\dashbox: Draw a dashed box. 
	\frame: Draw a frame around an object. 
	\framebox (picture): Draw a box with a frame around it. 
	\line: Draw a straight line. 
	\linethickness: Set the line thickness. 
	\makebox (picture): Draw a box of the specified size. 
	\multiput: Draw multiple instances of an object. 
	\oval: Draw an ellipse. 
	\put: Place an object at a specified place. 
	\shortstack: Make a pile of objects. 
	\vector: Draw a line with an arrow. 

############################################################
		\circle ::circle::
############################################################
\circle[*]{diameter} 
The \circle command produces a circle with a diameter as 
close to the specified one as possible. If the *-form of the 
command is used, LaTeX draws a solid circle. 
Note that only circles up to 40 pt can be drawn. 
############################################################
		\dashbox ::dashbox::
############################################################
Draws a box with a dashed line. 
\dashbox{dash_length}(width,height){...} 
The \dashbox has an extra argument which specifies the width 
of each dash. A dashed box looks best when the width and 
height are multiples of the dash_length. 
############################################################
		\frame ::frame::
############################################################
\frame{...} 
The \frame command puts a rectangular frame around the object 
specified in the argument. The reference point is the bottom 
left corner of the frame. No extra space is put between the 
frame and the object. 
############################################################
		\framebox ::framebox::
############################################################
\framebox(width,height)[position]{...} 
The \framebox command is exactly the same as the \makebox 
command, except that it puts a frame around the outside of 
the box that it creates. 

The framebox command produces a rule of thickness \fboxrule, 
and leaves a space \fboxsep between the rule and the contents 
of the box. 
############################################################
		\line ::line::
############################################################
\line(x slope,y slope){length} 
The \line command draws a line of the specified length and 
slope. 
Note that LaTeX can only draw lines with slope = x/y, where 
x and y have integer values from -6 through 6. 
############################################################
		\linethickness ::linethickness::
############################################################
\linethickness{dimension} 
Declares the thickness of horizontal and vertical lines in a 
picture environment to be dimension, which must be a positive 
length. It does not affect the thickness of slanted lines and 
circles, or the quarter circles drawn by \oval to form the 
corners of an oval. 
############################################################
		\makebox ::makebox::
############################################################
\makebox(width,height)[position]{...} 
The \makebox command for the picture environment is similar 
to the normal \makebox command except that you must specify 
a width and height in multiples of \unitlength. 
The optional argument, [position], specifies the quadrant 
that your text appears in. You may select up to two of the 
following: 
	t - Moves the item to the top of the rectangle 
	b - Moves the item to the bottom 
	l - Moves the item to the left 
	r - Moves the item to the right 
See section \makebox. 
############################################################
		\multiput ::multiput::
############################################################
\multiput(x coord,y coord)(delta x,delta y){number of copies}{object} 
The \multiput command can be used when you are putting the 
same object in a regular pattern across a picture. 
############################################################
		\oval ::oval::
############################################################
\oval(width,height)[portion] 
The \oval command produces a rectangle with rounded corners. 
The optional argument, [portion], allows you to select part 
of the oval. 
	t - Selects the top portion 
	b - Selects the bottom portion 
	r - Selects the right portion 
	l - Selects the left portion 
Note that the "corners" of the oval are made with quarter 
circles with a maximum 

radius of 20 pt, so large "ovals" will look more like boxes 
with rounded corners. 
############################################################
		\put ::put::
############################################################
\put(x coord,y coord){ ... } 
The \put command places the item specified by the mandatory 
argument at the given coordinates. 
############################################################
		\shortstack ::shortstack::
############################################################
\shortstack[position]{... \\ ... \\ ...} 
The \shortstack command produces a stack of objects. The 
valid positions are: 
	r - Moves the objects to the right of the stack 
	l - Moves the objects to the left of the stack 
	c - Moves the objects to the centre of the stack 
		(default) 
############################################################
		\vector ::vector::
############################################################
\vector(x slope,y slope){length} 
The \vector command draws a line with an arrow of the 
specified length and slope. The x and y values must lie 
between -4 and +4, inclusive. 

############################################################
	quotation ::quotation::
############################################################
 \begin{quotation}
  text
 \end{quotation}
The margins of the quotation environment are indented on the 
left and the right. 

The text is justified at both margins and there is paragraph 
indentation. 

Leaving a blank line between text produces a new paragraph. 
############################################################
	quote ::quote::
############################################################
 \begin{quote}
  text
 \end{quote}
The margins of the quote environment are indented on the left 
and the right. The text is justified at both margins. Leaving 
a blank line between text produces a new paragraph. 
############################################################
	tabbing ::tabbing::
############################################################
 \begin{tabbing}
 text \= more text \= still more text \= last text \\
 second row \>  \> more \\
 .
 .
 .
 \end{tabbing}
The tabbing environment provides a way to align text in 
columns. It works by setting tab stops and tabbing to them 
much the way you do with an ordinary typewriter. 

It is best suited for cases where the width of each column 
is constant and known in advance. 

This environment can be broken across pages, unlike the tabular 
environment. 

The following commands can be used inside a tabbing 
enviroment: 

############################################################
	\= ::=::
############################################################
Sets a tab stop at the current position. 
############################################################
	\> ::>::
############################################################
Advances to the next tab stop. 
############################################################
	\< ::<::
############################################################
This command allows you to put something to the left of the 
local margin without changing the margin. Can only be used 
at the start of the line. 
############################################################
	\+ ::+::
############################################################
Moves the left margin of the next and all the following 
commands one tab stop to the right. 
############################################################
	\- ::-::
############################################################
Moves the left margin of the next and all the following 
commands one tab stop to the left. 
############################################################
	\' ::'::
############################################################
Moves everything that you have typed so far in the current 
column, i.e. everything from the most recent \>, \<, \', \\, 
or \kill command, to the right of the previous column, flush 
against the current column's tab stop. 
############################################################
	\` ::`::
############################################################
Allows you to put text flush right against any tab stop, 
including tab stop 0. However, it can't move text to the right 
of the last column because here's no tab stop there. The \` 
command moves all the text that follows it, up to the \\ or 
\end{tabbing} command that ends the line, to the right margin 
of the tabbing environment. There must be no \> or \' command 
between the \` and the command that ends the line. 
############################################################
	\kill ::kill::
############################################################
Sets tab stops without producing text. Works just like \\ 
except that it throws away the current line instead of 
producing output for it. The effect of any \=, \+ or \- 
commands in that line remain in effect. 
############################################################
	\pushtabs ::pushtabs::
############################################################
Saves all current tab stop positions. Useful for temporarily 
changing tab stop positions in the middle of a tabbing 
environment. 
############################################################
	\pushtabs
############################################################
Restores the tab stop positions saved by the last \pushtabs. 
############################################################
	\a ::a::
############################################################
In a tabbing environment, the commands \=, \' and \` do not 
produce accents as normal. Instead, the commands \a=, \a' 
and \a` are used. 

This example typesets a Pascal function in a traditional 
format: 

        \begin{tabbing}
        function \= fact(n : integer) : integer;\\
                 \> begin \= \+ \\
                       \> if \= n $>$ 1 then \+ \\
                                fact := n * fact(n-1) \- \\
                          else \+ \\
                                fact := 1; \-\- \\
                    end;\\
        \end{tabbing}

############################################################
	table ::table::
############################################################

 \begin{table}[placement]

  body of the table

 \caption{table title}
 \end{table}

Tables are objects that are not part of the normal text, and 
are usually "floated" to a convenient place, like the top of 
a page. Tables will not be split between two pages.
 
The optional argument [placement] determines where LaTeX will 
try to place your table. There are four places where LaTeX 
can possibly put a float: 
	h : Here - at the position in the text where the table 
		environment appears. 
	t : Top - at the top of a text page. 
	b : Bottom - at the bottom of a text page. 
	p : Page of floats - on a separate float page, which 
		is a page containing no text, only floats. 
The standard report and article classes use the default 
placement [tbp]. 

The body of the table is made up of whatever text, LaTeX 
commands, etc., you wish. The \caption command allows you to 
title your table. 
############################################################
	tabular ::tabular::
############################################################

 \begin{tabular}[pos]{cols}
 column 1 entry & column 2 entry ... & column n entry \\
 .
 .
 .
 \end{tabular}

or 

 \begin{tabular*}{width}[pos]{cols}
 column 1 entry & column 2 entry ... & column n entry \\
 .
 .
 .
 \end{tabular*}

These environments produce a box consisting of a sequence of 
rows of items, aligned vertically in columns. The mandatory 
and optional arguments consist of: 
	width	Specifies the width of the tabular* environment. 
		There must be rubber space between columns that 
		can stretch to fill out the specified width. 
	pos	Specifies the vertical position; default is 
		alignment on the centre of the environment. 
		t - align on top row 
		b - align on bottom row 
	cols	Specifies the column formatting. It consists of 
		a sequence of the following specifiers, 
		corresponding to the sequence of columns and 
		intercolumn material. 
		l - A column of left-aligned items. 
		r - A column of right-aligned items. 
		c - A column of centred items. 
		| - A vertical line the full height and depth of 
			the environment. 
		@{text} - This inserts text in every row. An 
		  @-expression suppresses the intercolumn space 
		  normally inserted between columns; any desired 
		  space between the inserted text and the adjacent 
		  items must be included in text. An \extracolsep{wd} 
		  command in an @-expression causes an extra space 
		  of width wd to appear to the left of all subsequent 
		  columns, until countermanded by another \extracolsep 
		  command. Unlike ordinary intercolumn space, this 
		  extra space is not suppressed by an @-expression. 
		  An \extracolsep command can be used only in an 
		  @-expression in the cols argument. 
		p{wd} - Produces a column with each item typeset in 
		  a parbox of width wd, as if it were the argument 
		  of a \parbox[t]{wd} command. However, a \\ may not 
		  appear in the item, except in the following 
		  situations: 
			1. inside an environment like minipage, 
			   array, or tabular. 
			2. inside an explicit \parbox. 
			3. in the scope of a \centering, \raggedright, 
			   or \raggedleft 
		  declaration. The latter declarations must appear 
		  inside braces or an environment when used in a 
		  p-column element. 
		*{num}{cols} - Equivalent to num copies of cols, where 
		  num is any positive integer and cols is any list of 
		  column-specifiers, which may contain another 
		  *-expression.
 
These commands can be used inside a tabular environment: 

	\cline: Draw a horizontal line spanning some columns. 
	\hline: Draw a horizontal line spanning all columns. 
	\multicolumn: Make an item spanning several columns. 
	\vline: Draw a vertical line. 

############################################################
			\cline ::cline::
############################################################
\cline{i-j} 
The \cline command draws horizontal lines across the columns 
specified, beginning in column i and ending in column j, 
which are identified in the mandatory argument. 
############################################################
			\hline ::hline::
############################################################
The \hline command will draw a horizontal line the width of 
the table. It's most commonly used to draw a line at the top, 
bottom, and between the rows of the table. 
############################################################
			\multicolumn ::multicolumn::
############################################################
\multicolumn{cols}{pos}{text} 
The \multicolumn is used to make an entry that spans several 
columns. The first mandatory argument, cols, specifies the 
number of columns to span. The second mandatory argument, pos, 
specifies the formatting of the entry; c for centred, l for 
flushleft, r for flushright. The third mandatory argument, 
text, specifies what text is to make up the entry. 
############################################################
			\vline ::vline::
############################################################
The \vline command will draw a vertical line extending the 
full height and depth of its row. An \hfill command can be 
used to move the line to the edge of the column. It can also 
be used in an @-expression. 
############################################################
	thebibliography ::thebibliography::
############################################################
 \begin{thebibliography}{widest-label}
 \bibitem[label]{cite_key}
 .
 .
 .
 \end{thebibliography}
The thebibliography environment produces a bibliography or 
reference list. In the article class, this reference list is 
labelled "References"; in the report class, it is labelled 
"Bibliography". 

	widest-label: Text that, when printed, is 
		approximately as wide as the widest item 
		label produces by the \bibitem commands.
	\bibitem: Specify a bibliography item. 
	\cite: Refer to a bibliography item. 
	\nocite: Include an item in the bibliography. 
	Using BibTeX: Automatic generation of bibliographies. 

############################################################
			\bibitem ::bibitem::
############################################################
\bibitem[label]{cite_key} 
The \bibitem command generates an entry labelled by label. 
If the label argument is missing, a number is generated as 
the label, using the enumi counter. The cite_key is any 
sequence of letters, numbers, and punctuation symbols not 
containing a comma. This command writes an entry on the `.aux' 
file containing cite_key and the item's label. When this 
`.aux' file is read by the \begin{document} command, the 
item's label is associated with cite_key, causing the 
reference to cite_key by a \cite command to produce the 
associated label. 
############################################################
			\cite ::cite::
############################################################
\cite[text]{key_list} 
The key_list argument is a list of citation keys. This command 
generates an in-text citation to the references associated 
with the keys in key_list by entries on the `.aux' file read 
by the \begin{document} command. The optional text argument 
will appear after the citation, i.e. \cite[p. 2]{knuth} might 
produce `[Knuth, p. 2]'. 
############################################################
			\nocite ::nocite::
############################################################
\nocite{key_list} 
The \nocite command produces no text, but writes key_list, 
which is a list of one or more citation keys, on the `.aux' 
file. 
############################################################
			Using BibTeX
############################################################
If you use the BibTeX program by Oren Patashnik (highly 
recommended if you need a bibliography of more than a couple 
of titles) to maintain your bibliography, you don't use the 
thebibliography environment. Instead, you include the lines 

        \bibliographystyle{style} ::bibliographystyle::
        \bibliography{bibfile} ::bibliography::

where style refers to a file style.bst, which defines how 
your citations will look. The standard styles distributed 
with BibTeX are: 

	alpha	Sorted alphabetically. Labels are formed 
		from name of author and year of publication. 
	plain	Sorted alphabetically. Labels are numeric. 
	unsrt	Like plain, but entries are in order of 
		citation. 
	abbrv	Like plain, but more compact labels. 

In addition, numerous other BibTeX style files exist tailored 
to the demands of various publications. 
The argument to \bibliography refers to the file bibfile.bib, 
which should contain your database in BibTeX format. Only the 
entries referred to via \cite and \nocite will be listed in 
the bibliography. 
############################################################
	theorem ::theorem::
############################################################

 \begin{theorem}
  theorem text
 \end{theorem}

The theorem environment produces "Theorem x" in boldface 
followed by your theorem text. 
############################################################
	titlepage ::titlepage::
############################################################

 \begin{titlepage}
  text
 \end{titlepage}

The titlepage environment creates a title page, i.e. a page 
with no printed page number or heading. It also causes the 
following page to be numbered page one. 

Formatting the title page is left to you. The \today command 
comes in handy for title pages. 

Note that you can use the \maketitle (see section \maketitle) 
command to produce a standard title page. 
############################################################
	verbatim ::verbatim::
############################################################

 \begin{verbatim}
  text
 \end{verbatim}

The verbatim environment is a paragraph-making environment 
that gets LaTeX to print exactly what you type in. It turns 
LaTeX into a typewriter with carriage returns and blanks 
having the same effect that they would on a typewriter. 

	\verb: The macro form of the verbatim environment. 

############################################################
			\verb ::verb::
############################################################
\verb char literal_text char 
\verb*char literal_text char 
Typesets literal_text exactly as typed, including special 
characters and spaces, using a typewriter (\tt) type style. 
There may be no space between \verb or \verb* and char 
(space is shown here only for clarity). The *-form differs 
only in that spaces are printed as `\verb*| |'. 
############################################################
	verse ::verse::
############################################################
 \begin{verse}
  text
 \end{verse}
The verse environment is designed for poetry, though you may 
find other uses for it. 
The margins are indented on the left and the right. Separate 
the lines of each stanza with \\, and use one or more blank 
lines to separate the stanzas.
