There are many packages to do pictures in (La)TeX itself (rather than
importing graphics created externally), ranging from simple use of
LaTeX picture environment, through enhancements like epic, to
sophisticated (but slow) drawing with PicTeX. Depending on your type
of drawing, and setup, four systems should be at the top of your list
to look at:
graphics/pstricks; this gives you access to all the power of
PostScript from TeX itself, by sophisticated use of
\specials. You need a decent DVI to PostScript driver
(like dvips), but the results are worth it. The
well-documented package gives you not only low-level drawing
commands (and full colour) like lines, circles, shapes at arbitrary
coordinates, but also high-level macros for framing text, drawing
trees and matrices, 3D effects, and more.
graphics/mfpic) makes up METAFONT code for you
within using familiar-looking TeX macros. Not quite the
full power of METAFONT, but a friendlier interface.
macros/generic/dratex, which is as powerful as most
other TeX drawing packages, but is an entirely new
implementation, which is not as hard on memory, is much more
readable (and is fully documented).
Are you producing a thesis, and trying to obey regulations that were drafted in the typewriter era? Or are you producing copy for a journal that insists on double spacing for the submitted articles?
LaTeX is a typesetting system, so the appropriate design conventions are for ``real books''. If your requirement is from thesis regulations, find whoever is responsible for the regulations, and try to get the wording changed to cater for typeset theses (e.g., to say ``if using a typesetting system, aim to make your thesis look like a well-designed book''). (If your requirement is from a journal, you're probably even less likely to be able to get the rules changed, of course.)
If you fail to convince your officials, or want some inter-line space for copy-editing:
\baselinestretch:
\renewcommand{\baselinestretch}{1.2} may be enough to give
officials the impression you've kept to their regulations. Don't try
changing \baselineskip: its value is reset at any size-changing
command.
macros/latex/contrib/supported/setspace/setspace.sty
Thesis styles are usually very specific to your University, so it's
usually not profitable to ask around for a package outside your own
University. Since many Universities (in their eccentric way) still
require double-spacing, you may care to refer to
the question on double-spacing.
If you want to write
your own, a good place to start is the University of California style
(available as macros/latex/contrib/supported/ucthesis), but
it's not worth going to a lot of trouble. (If officials won't allow
standard typographic conventions, you won't be able to produce an
aesthetically pleasing document anyway!)
There are several LaTeX packages that purport to do this, but they all have their limitations because the TeX machine isn't really designed to solve this sort of problem. Piet van Oostrum has conducted a survey of the available packages; he recommends:
picins
picins.sty is part of a large package
(systems/msdos/picins/picins.zip) that allows inclusion of pictures (e.g., with
shadow boxes, various MS-DOS formats, etc.). The command is:
\parpic(width,height)(x-off,y-off)[Options][Position]{Picture}
Paragraph text
All parameters except the Picture are optional. The picture can be positioned left or right, boxed with a rectangle, oval, shadowbox, dashed box, and a caption can be given which will be included in the list of figures.
Unfortunately (for those of us whose understanding of German is not
good), the documentation is in German. Piet van Oostrum has written
an English summary macros/latex209/contrib/picins/picins.txt
floatflt
macros/latex/contrib/other/floatflt is an improved version
(for LaTeX2e) of floatfig.sty, and its syntax is:
\begin{floatingfigure}[options]{width of figure}
figure contents
\end{floatingfigure}
There is a (more or less similar) floatingtable environment.
The tables or figures can be set left or right, or alternating on even/odd pages in a double-sided document.
The package works with the multicol package, but doesn't work well
in the neighbourhood of list environments (unless you change your
LaTeX document).
wrapfig
macros/latex/contrib/other/misc/wrapfig.sty has syntax:
\begin{wrapfigure}[height of figure in lines]{l|r}[overhang]{width}
figure, caption, etc.
\end{wrapfigure}
The syntax of the wraptable environment is similar.
Height can be omitted, in which case it will be calculated by the
package; the package will use the greater of the specified and the
actual width. The {l,r,etc.} parameter can also be
specified as i(nside) or o(utside) for two-sided
documents, and uppercase can be used to indicate that the picture
should float. The overhang allows the figure to be moved into the
margin. The figure or table will entered into the list of figures
or tables if you use the \caption command.
The environments do not work within list environments that end before the figure or table has finished, but can be used in a parbox or minipage, and in twocolumn format.
The standard LaTeX document classes define a small set of `page styles' which (in effect) specify head- and footlines for your document. The set defined is very restricted, but LaTeX is capable of much more; people occasionally set about employing LaTeX facilities to do the job, but that's quite unnecessary - Piet van Oostrum has already done the work.
The package is found in directory macros/latex/contrib/supported/fancyhdr and provides
simple mechanisms for defining pretty much every head- or footline
variation you could want; the directory also contains some (rather
good) documentation and one or two smaller packages. Fancyhdr
also deals with the tedious behaviour of the standard styles with
initial pages,
by enabling you to define
different page styles for initial and for body pages.
A good way is to use Rainer Schöpf's verbatim.sty,
which provides a command \verbatiminput that takes a file name
as argument. This package is available as part of macros/latex/required/tools
Another way is to use the alltt environment, which requires
alltt.sty (which is now part of LaTeX). alltt interprets
its contents `mostly' verbatim, but executes any TeX commands it
finds: so one can say:
\begin{alltt}
\input{verb.txt}
\end{alltt}
of course, this is little use for inputting (La)TeX source code...
The moreverb package (macros/latex/contrib/supported/moreverb) extends the
facilities of verbatim package), providing a listing
environment and a \listinginput command, which line-number the text
of the file.
The fancyvrb package (macros/latex/contrib/supported/fancyvrb) offers configurable
implementations of everything verbatim and moreverb
have, and more besides. It is nowadays the package of choice for the
discerning typesetter of verbatim text, but its wealth of facilities
makes it a complex beast and study of the documentation is strongly
advised.
For general numbering of lines, there are two packages for use with
LaTeX, macros/latex/contrib/supported/lineno (which permits labels attached to
individual lines of typeset output) and macros/latex/contrib/supported/numline/numline.sty
Both of these packages play fast and loose with the LaTeX output routine, which can cause problems: the user should beware\dots
If the requirement is for numbering verbatim text, the
macros/latex/contrib/supported/moreverb or macros/latex/contrib/supported/fancyvrb packages (see
including files in verbatim) may be used.
One common use of line numbers is in critical editions of texts, and
for this the edmac package (macros/plain/contrib/edmac) offers comprehensive
support.
Making an index is not trivial; what to index, and how to index it, is
difficult to decide, and uniform implementation is difficult to
achieve. You will need to mark all items to be indexed in your text
(typically with \index commands).
It is not practical to sort a large index within TeX, so a post-processing program is used to sort the output of one TeX run, to be included into the document at the next run.
The following programs are available:
indexing/makeindex; a version for
the Macintosh is available as systems/mac/macmakeindex.sit, and ones for
MS-DOS are part of the emTeX and gTeX distributions (the
emTeX version also runs under OS/2).
The Makeindex documentation is a good source of information on how
to create your own index. Makeindex can be used with some TeX
macro packages other than LaTeX, such as
Eplain, and \TeXsis{}, nonfree/macros/texsis
(whose macros, nonfree/macros/texsis/index/index.tex, can be used independently
with plain).
glotex) in indexing/glo+idxtex
support/texindex
There are other programs called texindex, notably one that comes with the Texinfo distribution.
support/xindy), but is more easily accessed from a web
browser via http://www.iti.informatik.th-darmstadt.de/xindy/
since the distribution contains several different implementations.
URLs tend to be very long, and contain characters that would
naturally prevent them being hyphenated even if they weren't typically
set in \ttfamily, verbatim. Therefore, without special treatment,
they often produce wildly overfull \hboxes, and their typeset
representation is awful.
There are two approaches to this problem:
macros/latex/contrib/other/misc/path.sty, which defines a \path command. The command
defines each potential break character as a \discretionary, and
offers the user the opportunity of specifying a personal list of
potential break characters. Its chief disadvantage is fragility in
the LaTeX context.
macros/latex/contrib/other/misc/url.sty, which defines an \url command (among others,
including its own \path command). The command gives each
potential break character a maths-mode `personality', and then sets
the URL itself in the user's choice of font, in maths mode.
It can produce (LaTeX-style) `robust' commands
(see use of \protect) for use
within moving arguments. Note that, because the operation is
conducted in maths mode, spaces within the URL argument are
ignored unless special steps are taken.
The author of this answer prefers the (rather newer) url.sty;
both packages work equally well with plain TeX (though of course,
the fancy LaTeX facilities of url.sty don't have much place
there).
There is no citation type for URLs, per se, in the standard BibTeX styles, though Oren Patashnik (the author of BibTeX) is considering developing one such for use with the long-awaited BibTeX version 1.0.
The actual information that need be available in a citation of an
URL is discussed at some length in the publicly available
on-line extracts of ISO 690-2, available via
http://www.nlc-bnc.ca/iso/tc46sc9/standard/690-2e.htm; the
techniques below do not satisfy all the requirements of
ISO 690-2, but they offer a solution that is at least
available to users of today's tools.
Until the new version arrives, the simplest technique is to use the
howpublished field of the standard styles' @misc function. Of
course, the strictures
about typesetting URLs
still apply, so the entry will look like:
@misc{...,
...,
howpublished = "\url{http://...}"
}
Another possibility is that some conventionally-published paper, technical report (or even book) is also available on the Web. In such cases, a useful technique is something like:
@techreport{...,
...,
note = "Also available as \url{http://...}"
}
There is good reason to use macros/latex/contrib/other/misc/url.sty in this context, since (by
default) it ignores spaces in its argument. BibTeX has a habit of
splitting lines it considers excessively long, and if there are no
space characters for it to use as `natural' breakpoints, BibTeX
will insert a comment (`\textpercent')
character ... which is an acceptable character in an URL,
so that \url will typeset it. The way around the problem is to
insert odd spaces inside the URL itself in the .bib file, to
enable BibTeX to make reasonable decisions about breaking the
line.
plain TeX
The file macros/eplain/btxmac.tex contains macros and documentation
for using BibTeX with plain TeX, either directly or with
Eplain.

A powerful package which allows the typesetting of
polyphonic and other multiple-stave music is MusicTeX, written by
Daniel Taupin
([email protected]). It is available
in macros/musictex
In the recent past, Daniel (as well as with various other people,
notably Ross Mitchell and Andreas Egler) have been working on a development of
MusicTeX, known as MusiXTeX. MusiXTeX is a three-pass
system (with a processor program that computes values for the element
spacing in the music), and achieves finer control than is possible in
the unmodified TeX-based mechanism that MusicTeX uses. Daniel
Taupin and Andreas Egler are pursuing distinct versions of
MusiXTeX; they are available, respectively, from
macros/musixtex/taupin and macros/musixtex/egler
Digital music fans can typeset notation for their efforts by using
midi2tex, which translates MIDI data files into MusicTeX
source code. It is available from support/midi2tex
A rather simpler notation than MusicTeX is supported by abc2mtex;
this is a package designed to notate tunes stored in an ASCII format
(abc notation). It was designed primarily for folk and traditional
tunes of Western European origin (such as Irish, English and Scottish)
which can be written on one stave in standard classical notation.
However, it should be extendable to many other types of music. It is
available from support/abc2mtex
There is a mailing list for discussion of typesetting music in TeX.

Michael Levine's macro package for drawing Feynman diagrams in LaTeX
is available in macros/latex209/contrib/feynman
Another possibility is Thorsten Ohl's macros/latex/contrib/supported/feynmf, that works in
combination with METAFONT (or MetaPost). The feynmf or
feynmp package reads a description of the diagram written
in TeX, and writes out code. METAFONT (or MetaPost) can then produce a
font (or PostScript file) for use in a subsequent LaTeX run. For
new users, who have access to MetaPost, the PostScript version is
probably the better route, for document portability and other reasons.
