+ ========================  physymb  ============================
+ Created by David Zaslavsky <diazona@ellipsix.net>
+
+The physymb package contains a bunch of assorted macros that may
+be useful to physicists (and perhaps occasionally mathematicians).
+
+The package contains five files:
+
+* README: This file :)
+* physymb.sty: The package itself.
+* physymb.pdf: The PDF documentation, which details all the macros
+   defined by the package.
+* physymb.dtx: The documented source. Running pdflatex on this
+   reproduces the PDF documentation.
+* physymb.ins: The installer file. Running latex or pdflatex on
+   this will regenerate physymb.sty.
+
+To install the package, it should be enough to just copy physymb.sty
+to the tex/latex/physymb/ directory (which you may need to create)
+within your local TDS tree, which is typically $HOME/texmf/ on
+a Linux system. The location varies on Windows. It's also recommended
+to copy physymb.pdf into doc/latex/physymb/ under the TDS tree.
+
+If you don't know what a TDS tree is, or want to have this explained
+in more detail, see
+http://www.tex.ac.uk/cgi-bin/texfaq2html?label=instpackages

+%
+% \maketitle
+% \begin{abstract}
+%  The |physymb| package is nothing but a bunch of simple macro definitions that
+%  may be useful for typesetting physics papers.
+% \end{abstract}
+%
+% \paragraph{What's so great about it?}
+% If you're scanning over this document wondering what good a bunch of simple macro
+% definitions are, allow me to point out some highlights:
+% \begin{itemize}
+%  \item Total and partial derivatives can be typeset using two character macros.\\
+%   $\ud{y}{x}$ is now as easy as |\ud{y}{x}|.
+%  \item Numbers in scientific notation can also be typeset using a two character macro.
+%   $\sn{6.23}{6}$ is written |\sn{6.23}{6}|.
+%  \item Doing the same thing with units added is similarly convenient; you can write
+%   $\snunit{3.1}{6}{\meter^3}$ as |\snunit{3.1}{6}{\meter^3}|, which is a lot more
+%   convenient than writing the whole thing out ``manually.''
+%  \item There are standard, simple macros for writing Dirac notation: $\ket{\psi}$ is
+%   as easy as |\ket{\psi}|.
+% \end{itemize}
+%
+% There are a lot of macros in this package, and it typically doesn't take as many
+% lines to explain their meanings as it does to list them all. For that reason, when
+% there are a bunch of similar macros that I explain together, I've usually only listed
+% one or two in the left margin. In these cases, all the macros are given in the text.
+%
+% \section{Options}
+%
+% |physymb| recognizes the following options, in no particular order.
+%
+% \begin{itemize}
+%  \item |arrowvectors| causes vectors (specifically, the |\vec| command) to be rendered
+%   with an arrow above the symbol.
+%  \item |boldvectors| causes vectors (again, from |\vec|) to be rendered by typesetting
+%   the symbol in bold. It's the alternative to |arrowvectors|.
+%  \item |feynman| pulls in the |feynmp| package. (It's precisely equivalent to
+%   |\usepackage{feynmp}|, it's just here for convenience.)
+%  \item |particle| enables all the particle physics macros. (It's actually not implemented
+%   yet, so in practice the particle macros get defined regardless of whether you pass this
+%   option or not, but that will be fixed soon.)
+%  \item |units| pulls in the |SIunits| package and enables the additional unit macros.
+% \end{itemize}
+%
+% \section{Macros}
+%
+% \subsection{Trigonometry}
+%
+% \DescribeMacro{\asin}
+% \DescribeMacro{\acos}
+% The AMS packages only define inverse trigonometric functions using the ``arc''
+% syntax, i.e. they actually prefix ``arc'' to the name (as in $\arcsin x$).
+% Sometimes you'd rather write them with a superscript $-1$ to save space, so
+% those versions are included here. We have the inverse functions |\asin|,
+% |\acos|, |\atan|, |\asec|, |\acsc|, and |\acot|.
+%
+% \DescribeMacro{\sech}
+% \DescribeMacro{\cosh}
+% For some reason, the hyperbolic sine and cosine |\sech| and |\cosh| aren't
+% defined in the AMS packages. This fixes that.
+%
+% \DescribeMacro{\asinh}
+% \DescribeMacro{\acosh}
+% Finally, the inverse hyperbolic trig functions written with the superscript
+% $-1$ are defined just as with the regular inverse trig functions. We have
+% |\asinh|, |\acosh|, |\atanh|, |\asech|, |\acsch|, and |\acoth|.
+%
+% \subsection{Sets}
+%
+% There are certain sets of numbers that are semi-frequently referenced in physics.
+% Typically they're used to say something like $n\in\intset$. Of course, a
+% macro like |\intset| is not necessarily much quicker than writing
+% |\mathbb{Z}|, but these macros are intended to have names that relate to
+% their meanings so that you don't have to remember which letter goes to which set.
+%
+% \DescribeMacro{\whlset}
+% |\whlset| ($\whlset$) denotes the set of whole numbers, which is typically
+% defined to include all integers greater than zero, although there are different
+% contradictory definitions floating around.
+%
+% \DescribeMacro{\natset}
+% |\natset| ($\natset$) denotes the set of natural numbers, which is typically
+% defined to include all integers greater than or equal to zero. Some people
+% define ``natural numbers'' to exclude zero.
+%
+% \DescribeMacro{\intset}
+% |\intset| ($\intset$) denotes the set of all integers.
+%
+% \DescribeMacro{\realset}
+% |\realset| ($\realset$) denotes the set of all real numbers.
+%
+% \DescribeMacro{\imagset}
+% |\imagset| ($\imagset$) denotes the set of all imaginary numbers, which is
+% all complex numbers with real part equal to zero. This one is infrequently
+% used.
+%
+% \DescribeMacro{\cpxset}
+% |\cpxset| ($\cpxset$) denotes the set of all complex numbers.
+%
+% \subsection{Calculus}
+%
+% Probably the most useful macros in the package are the derivative operators.
+% Since it's so common to write something of the form $\ud{y}{x}$ or $\pd{y}{x}$,
+% we have two-character macros for each:
+% \begin{itemize}
+%  \item \DescribeMacro{\ud} |\ud|\marg{top}\marg{bottom} typesets the normal total derivative
+%  \item \DescribeMacro{\pd} |\pd|\marg{top}\marg{bottom} typesets a partial derivative, which
+%   is the same thing but with a partial derivative symbol instead of the $\udc$.
+% \end{itemize}
+% \DescribeMacro{\udd}
+% \DescribeMacro{\uddd}
+% \DescribeMacro{\pdd}
+% \DescribeMacro{\pddd}
+% There are variants of these that produce higher-order derivatives; you can add
+% an order by adding another |d|, up to a total of three.
+% If you need something higher than the third derivative, you're on your own, but it's
+% easy to construct it using |\frac| and |\udc| or |\pdc|,
+% \begin{center}
+%  |\frac{\udc^4 y}{\udc x^4}|
+% \end{center}
+%
+% \DescribeMacro{\udc}
+% \DescribeMacro{\pdc}
+% The macro |\udc| gives you the character that represents a differential. It's typically
+% set in roman type to distinguish it from a variable. |\pdc| is also defined as the
+% partial derivative character for consistency. There are variants of each with exponents
+% (up to 3) built in; again, you get them by adding an extra |d| or two to the name of the
+% command, |\uddc| and |\udddc| and so on.
+%
+% \DescribeMacro{\uds}
+% \DescribeMacro{\pds}
+% If you're using these in an integral, it's common to want a small space before the
+% differential, so there are variants of the preceding commands defined that include
+% this small space for you; they replace the |c| with an |s|. They follow the same
+% pattern of adding additional |d|'s to get exponents. For example:
+%
+% \begin{minipage}{.64\textwidth}
+% \begin{center}
+%  |\iint e^{i\vec{k}\cdot\vec{x}}\udds\vec{x}|
+% \end{center}
+% \end{minipage}
+% \begin{minipage}{.34\textwidth}
+% \begin{equation*}
+%  \iint e^{i\vec{k}\cdot\vec{x}}\udds\vec{x}
+% \end{equation*}
+% \end{minipage}
+%
+% \subsection{Vector Calculus}
+%
+% \DescribeMacro{\div}
+% \DescribeMacro{\grad}
+% \DescribeMacro{\curl}
+% |\physymb| defines |\div|, |\grad|, and |\curl|, to represent the
+% divergence, gradient, and curl. These are typeset with the nabla
+% (or ``del'') character, $\nabla$, rather than being written out
+% as words. Naturally, I would love to add an |\allthat| if I can
+% find something good for it to represent.
+%
+% \DescribeMacro{\lapl}
+% There is also a macro for the Laplacian operator (divergence of a
+% gradient), |\lapl|.
+%
+% \subsection{Complex Analysis}
+%
+% \DescribeMacro{\conj}
+% There is a macro to indicate the conjugate of a number, |\conj|\marg{number}.
+% It puts a superscript star after the number, as in $\conj{z}$.
+%
+% \DescribeMacro{\realop}
+% \DescribeMacro{\imagop}
+% The traditional keywords indicating the real and imaginary parts of a complex number
+% are given macros |\realop| and |\imagop|. They typeset $\realop$ and $\imagop$
+% respectively.
+%
+% \DescribeMacro{\real}
+% \DescribeMacro{\imag}
+% Why the |op|? Well, there are alternate versions that will also put curly braces
+% around the following argument, |\real| and |\imag|. This is the way $\realop$ and
+% $\imagop$ are often used.
+%
+% \begin{minipage}{.64\textwidth}
+% \begin{center}
+%  |\real{z}, \imag{z}|
+% \end{center}
+% \end{minipage}
+% \begin{minipage}{.34\textwidth}
+% \begin{equation*}
+%  \real{z}, \imag{z}
+% \end{equation*}
+% \end{minipage}
+%
+% \DescribeMacro{\abs}
+% The macro |\abs|\marg{value} surrounds its argument with vertical bars.
+%
+% \subsection{Linear Algebra}
+%
+% There are several assorted macros for linear algebra keywords and concepts.
+%
+% \DescribeMacro{\vec}
+% \DescribeMacro{\vecvar}
+% Vectors can be written using the macro |\vec|\marg{label}, which typesets
+% the \meta{label} either in bold or with an arrow over it, according to which
+% option was passed to the package (|arrowvectors| or |boldvectors|).
+% The default is to use an arrow, to resemble the builtin definition of
+% |\vec| (which, by the way, is overridden by this package). In many cases
+% I prefer bold. |\vecvar|\marg{label} is another macro that does the exact
+% same thing, for consistency with the other kinds of variables.
+%
+% \DescribeMacro{\tnsvar}
+% The macro |\tnsvar|\marg{label} is for typesetting tensors. This just makes
+% the \meta{label} bold, it doesn't do anything with indices. If you want a way
+% to typeset tensor indices, look at the
+% \href{http://tug.ctan.org/cgi-bin/ctanPackageInformation.py?id=tensor}{tensor}
+% package.
+%
+% \DescribeMacro{\matvar}
+% |\matvar|\marg{label} is intended to designate matrices. It makes the label
+% bold.
+%
+% \DescribeMacro{\identitym}
+% The macro |\identitym| represents the identity matrix. It typesets a 1 in
+% the same style as |\matvar| (so, bold).
+%
+% \DescribeMacro{\determinant}
+% The macro |\determinant|\marg{matrix} uses vertical bars to denote the determinant
+% of the \meta{matrix}. It's an alternative to the keyword operator |\det|, which
+% just typesets as $\det$.
+%
+% \DescribeMacro{\trace}
+% The macro |\trace| just typesets $\trace$. It's akin to |\det|.
+%
+% \DescribeMacro{\diag}
+% This just typesets $\diag$, which is used to represent a matrix with the given entries
+% on the diagonal. For example, one might write |\diag(1,2,3,4)|.
+%
+% \DescribeMacro{\norm}
+% The norm of a vector can be denoted by double vertical bars. This is implemented by
+% |\norm|\marg{value}.
+%
+% \DescribeMacro{\unitx}
+% \DescribeMacro{\unity}
+% \DescribeMacro{\unitz}
+% Since it's so common to refer to unit vectors using hat notation, there are a
+% bunch of macros for them using various letters. The package defines |\unitd|,
+% |\unite|, |\uniti|, |\unitj|, |\unitk|, |\unitl| (which typesets as $\unitl$,
+% not the normal $l$), |\unitn|, |\unitp|, |\unitq|, |\unitr|, |\units|, |\unitt|,
+% |\unitu|, |\unitv|, |\unitw|, |\unitx|, |\unity|, |\unitz|, and for non-roman
+% characters, |\unitphi|, |\unitrho|, |\unittheta|, and |\unitomega|.
+% \DescribeMacro{\unitvec}
+% If you want to use a different letter as a unit vector, it can be done with
+% |\unitvec|\marg{symbol}.
+%
+% \DescribeMacro{\herm}
+% |\herm|\marg{operator} designates the hermitian conjugate of an operator with
+% a superscript dagger.
+%
+% \DescribeMacro{\transpose}
+% |\transpose|\marg{matrix} sets a superscript $T$ after the matrix to denote
+% the transpose.
+%
+% \DescribeMacro{\commut}
+% \DescribeMacro{\acommut}
+% There are simple macros for the commutator, |\commut|\marg{operator}\marg{operator},
+% and the anticommutator, |\acommut|\marg{operator}\marg{operator}. They just
+% put the appropriate kind of braces around the arguments (and the comma between
+% them, of course).
+%
+% \subsection{Differential Geometry}
+% \DescribeMacro{\exd}
+% The exterior derivative has a macro, |\exd|, kind of like the macro for differentials
+% ($\udc$) although typeset in bold to distinguish it. This one doesn't have any variants,
+% though, because $\exd^2 = 0$.
+%
+% \DescribeMacro{\hodge}
+% The macro |\hodge| just puts a star (not superscript) to represent the Hodge dual.
+% Use it as a prefix to the variable, $\hodge\exd x$.
+%
+% \subsection{Classical Mechanics}
+%
+% \DescribeMacro{\pbrac}
+% The Poisson brackets of a pair of variables can be typeset using the macro
+% |\pbrac|\marg{function}\marg{function}. This just surrounds the two arguments
+% with curly braces, producing $\pbrac{f}{g}$.
+%
+% \DescribeMacro{\pbracvars}
+% If you want to specify which variables the derivatives in the Poisson brackets
+% are being taken with respect to, use the variant
+% \begin{center}
+%  |\pbracvars|\marg{function}\marg{function}\marg{variable}\marg{variable}
+% \end{center}
+% It comes out looking like $\pbracvars{f}{g}{q}{p}$.
+%
+% \subsection{Quantum Mechanics}
+%
+% |physymb| includes a full set of macros for working with Dirac notation.
+%
+% \DescribeMacro{\ket} To typeset a ket ($\ket\psi$), use |\ket|\marg{label}.
+% \DescribeMacro{\bra} Similarly, you can get a bra ($\bra\psi$), with |\bra|\marg{label}.
+% \DescribeMacro{\braket} To typeset a bracket (inner product), use
+% |\braket|\marg{bra label}\marg{ket label}.
+%
+% \DescribeMacro{\melement} To typeset a matrix element ($\melement{\phi}{A}{\psi}$), or any
+% case in which you have an operator between the bra and the ket, use
+% |\melement|\marg{bra label}\marg{operator}\marg{ket label}.
+% It should work fine to put an arbitrarily complicated expression in the middle of |\melement|,
+% but if your operator is something complicated, you \emph{could} consider just using |\bra|
+% and |\ket| for clarity,
+% \begin{center}
+%  |\bra{|\meta{bra label}|}|\meta{operator}|\ket{|\meta{ket label}|}|
+% \end{center}
+%
+% \DescribeMacro{\expect} To get an expectation value (an on-diagonal matrix element with
+% the state left implicit, $\expect{A}$), use |\expect|\marg{operator}. Again, you can put
+% an arbitrary expression within |\expect| but if it would make the code unclear, consider
+% using |\langle| and |\rangle|.
+%
+% \DescribeMacro{\projop} For a projection operator (outer product between a state and itself),
+% we have the command |\projop|\marg{label}\marg{value}, which comes out as $\projop{\psi}{x}$.
+% To get a general outer product between two different states, use |\bra| and |\ket|,
+% \begin{center}
+%  |\ket{|\meta{ket label}|}|\meta{value}|\bra{|\meta{bra label}|}|
+% \end{center}
+%
+% \subsection{Units}
+%
+% If the |units| option is provided to |physymb|, it automatically includes the |SIunits|
+% package and defines some additional units that are often useful in practice.
+%
+% \DescribeMacro{\snunit} |\snunit|\marg{abcissa}\marg{exponent}\marg{unit} combines
+% the functionality of |\sn| and |\unit|: it typesets a number in scientific notation
+% with a following unit. If the abcissa is equal to $1$, it is omitted, so that
+% |\snunit{1}{6}{\meter}| gives you $\snunit{1}{6}{\meter}$.
+%
+% \paragraph{SI units}
+% \DescribeMacro{\joulepercubicmeter}
+% \DescribeMacro{\joulepercubicmeterrp}
+% These units of energy density have been useful to me approximately twice.
+% Naturally, I had to include them. These augment the list of
+% composite units made available by |SIunits| itself.
+%
+% \paragraph{Additional units} The |SIunits| package only includes SI units (as
+% the name would suggest), but there are certain non-SI units that turn out to
+% be occasionally useful when dealing with American non-scientists. |physymb|
+% defines a selection of them as macros.
+%
+% \DescribeMacro{\torr}
+% \DescribeMacro{\mmHg}
+% Torr, |\torr|, and millimeters of mercury, |\mmHg|, are common atmospheric pressure units.
+%
+% \DescribeMacro{\amu}
+% |\amu| represents the atomic mass unit, defined as $\frac{1}{12}$ of the mass of a carbon 12
+% atom.
+%
+% \DescribeMacro{\yr}
+% |\yr| represents a year with the symbol $\yr$. There are various definitions of
+% different kinds of years floating around, but generally the symbol is the same.
+%
+% \DescribeMacro{\erg}
+% |\erg| represents an erg, the CGS unit of energy, which still finds occasional use.
+% Its value is $\snunit{1}{-7}{\joule}$.
+%
+% \DescribeMacro{\gauss}
+% |\gauss| is the Gauss, a unit of magnetic field equal to $\snunit{1}{-4}{\tesla}$.
+%
+% \DescribeMacro{\molar}
+% |\molar| represents a molar, a unit of concentration equal to one mole per liter.
+% Strictly speaking, this is a chemistry unit, but it occasionally comes up in
+% physics so it shouldn't hurt to have the macro around.
+%
+% \DescribeMacro{\poise}
+% The poise is the CGS unit of viscosity, equal to $\unit{0.1}{\pascal\usk\second}$.
+%
+% \DescribeMacro{\foot}
+% The foot is the Imperial unit of length, equal to $\unit{30.48}{\centi\meter}$.
+%
+% \DescribeMacro{\mileperhour}
+% This is typically (or perhaps almost exclusively) used to measure transportation
+% speeds: cars, trains, airplanes, etc. It's equal to about
+% $\unit{0.447}{\frac{\meter}{\second}}$.
+%
+% \DescribeMacro{\pound}
+% The pound is the Imperial unit of either force or mass, depending on who you
+% ask. Technically I believe it is a force, but in many situations
+% I've often found it clearer to treat it as a unit of mass and use $\mathrm{lbf}$
+% (pound of force) as the unit of force. In this sense, it's equal to about
+% $\unit{453.59}{\gram}$, and the pound of force is the weight of that mass
+% under standard Earth surface gravity, which works out to about
+% $\unit{4.448}{\newton}$.
+%
+% \subsection{Particle Physics}
+%
+% As a particle physicist, I do a lot of work that involves notation for elementary particles,
+% so it's become useful to have a set of macros that produce standard written representations
+% for them.\footnote{If there are other areas of physics in which a lot of short macros like
+% these would be useful, I'm open to suggestions for adding them.} The names of the commands
+% are pretty cryptic, but I've found that once you get used to using them, the names aren't
+% hard to remember and the effort saved by having short macro names at least \emph{feels}
+% worthwhile.
+%
+% In general, all the macro names follow the same pattern. Each one ends with a type
+% code that identifies the type of particle: |q| for quark, |lp| for a ``regular'' lepton,
+% |nu| for a neutrino, |br| for a baryon, |m| for a meson, and |bsn| for a boson. At the
+% beginning is a particle code consisting of one or two letters that identify the specific
+% particle within that type.
+%
+% Most of the basic macros consist of just those two parts. Antifermion macros are
+% constructed by prepending an |a| to the type code. For vector bosons that occur in
+% charge triplets, you prepend one of |p| (plus), |z| (zero), or |m| (minus) to indicate
+% which one of the triplet you want. The same goes for baryons which occur in ``triplets''
+% with the same name (three particles denoted by the same letter, even though they
+% may not actually be a triplet). Singlet baryons have the |z| as well for consistency.
+%
+% The proton and neutron are named differently because their names are so common.
+%
+% \paragraph{Quarks}
+% \DescribeMacro{\upq}
+% \DescribeMacro{\dnq}
+% Each of the quark macros is named with three letters. The first two letters are the
+% particle code representing the name of the quark, and the third is the type code |q|.
+% The macros are |\upq|, |\dnq|, |\srq|, |\chq|, |\btq|, and |\tpq|, representing the
+% up, down, strange, charm, bottom, and top quarks, respectively.
+%
+% \DescribeMacro{\upaq}
+% \DescribeMacro{\dnaq}
+% The corresponding macros for the antiquarks are obtained by prepending |a| to the
+% type code |q|. We have |\upaq|, |\dnaq|, |\sraq|, |\chaq|, |\btaq|, and |\tpaq|.
+%
+% \paragraph{Leptons}
+% \DescribeMacro{\elp}
+% \DescribeMacro{\enu}
+% Leptons are done a little differently because there are two distinct types. The macros for
+% the electron, muon, and tau lepton are named with a letter and |lp|: we have |\elp| for the
+% electron, |\ulp| for the muon, and |\tlp| for the tau. Neutrino macros are constructed
+% using the same first letter, but |nu| instead of |lp|: |\enu|, |\unu|, and |\tnu|.
+%
+% \DescribeMacro{\ealp}
+% \DescribeMacro{\eanu}
+% Antileptons are named with an |a| between the particle code and the type code.
+% So we get |\ealp|, |\ualp|, and |\talp| for the ``regular'' antileptons and
+% |\eanu|, |\uanu|, and |\tanu| for the antineutrinos.
+%
+% \paragraph{Baryons}
+% \DescribeMacro{\lmzbr}
+% \DescribeMacro{\sgpbr}
+% \DescribeMacro{\sgzbr}
+% \DescribeMacro{\sgmbr}
+% Many of the most commonly referenced baryons in the standard model have
+% macros defined. Each of these ends with the type code |br|. Most of them are built
+% by putting a particle code and a charge letter together: we have |\lmzbr| for the
+% lambda baryon; |\sgpbr|, |\sgzbr|, |\sgmbr| for the sigmas, |\xizbr| and |\ximbr|
+% for the xi particles, and |\ommbr| for the omega of charge $-1$. The delta macros
+% are named on the same principle but since there are four of them, we use two charge
+% letters to indicate the $+2$ charge: |\dlppbr|, |\dlpbr|, |\dlzbr|, and |\dlmbr|.
+%
+% \DescribeMacro{\sgspbr}
+% \DescribeMacro{\sgszbr}
+% \DescribeMacro{\sgsmbr}
+% In addition, there are macros for the starred (excited) versions of the sigmas and
+% xis (only), obtained by adding an |s| before the charge letter: |\sgspbr| etc. and
+% |\xiszbr| etc.
+%
+% \DescribeMacro{\prbr}
+% \DescribeMacro{\nebr}
+% The proton and neutron don't quite fall into the pattern because their names aren't
+% used for multiple particles. The proton is |\prbr| and the neutron is |\nebr|.
+%
+% \DescribeMacro{\dlmmabr}
+% The antiparticles to all these are obtained in \emph{almost} the usual way, by
+% adding |a| just before the type code |br|. The one difference is that the charge
+% letters are updated to reflect the actual charge of the antiparticle, so for example
+% the antipartcle of the $\dlppbr$ (|\dlppbr|), the $\dlmmabr$, is written |\dlmmabr|,
+% with two |m|'s because of its double-minus charge.
+%
+% \paragraph{Mesons}
+% \DescribeMacro{\pipm}
+% \DescribeMacro{\pizm}
+% \DescribeMacro{\pimm}
+% Essentially all the mesons defined in the standard model have macros. The naming can
+% be a bit tricky because some of them are named as charge triplets while others are
+% named as antiparticles. In the former case, we have the $\pi$s, |\pipm|, |\pizm|, and |\pimm|,
+% and the $\rho$s, |\ropm|, |\rozm|, and |\romm|. (I'm not sure if it'd make it cleaner
+% to just add the |h| into the names) The kaons have similar names, |\kapm|,
+% |\kazm|, and |\kamm|, but there is also the $\kazam$, |\kazam|. Finally, the neutral
+% mesons are named |\etam|, |\etapm| (here the |p| is for ``prime,'' not ``plus''), and
+% |\phim|.
+%
+% \paragraph{Bosons}
+% \DescribeMacro{\phbsn}
+% \DescribeMacro{\Wpbsn}
+% \DescribeMacro{\Wmbsn}
+% There aren't that many bosons so the naming is simple: |\phbsn| for the photon,
+% |\Zzbsn| for the neutral $\Zzbsn$, and |\Wpbsn| and |\Wmbsn| for the $\Wbsn$s. There's
+% also |\Wbsn|, which does not indicate either charge, for when you need to refer to
+% a generic $\Wbsn$ boson. The Higgs boson is written |\hbsn|.
+%
+% \DescribeMacro{\photon}
+% Also, there is a macro |\photon| which is defined to be the same thing as |\phbsn|.
+% It's included to support some old LaTeX files I wrote and although it will
+% \emph{probably} not be removed from the package in the future, I make no guarantees.
+%
+% \subsection{Miscellaneous}
+%
+% \DescribeMacro{\sn} |\sn|\marg{abcissa}\marg{exponent} is a shorthand for setting a number
+% in scientific notation. It works just like |\snunit| except that it does not take any unit
+% as an argument.
+%
+% \DescribeMacro{\scriptr} |\scriptr| produces the script r found in Griffiths'
+% electromagnetism textbook, or at least the closest equivalent in LaTeX, $\scriptr$.
+%
+% \DescribeMacro{\orderof} |\orderof|\marg{expression} represents the order of an
+% expression, for example the error term in a perturbation series. Typical usage
+% would be like
+%
+% \begin{minipage}{.64\textwidth}
+% \begin{center}
+%  |\frac{1}{1 - x} = 1 + x + \orderof{x^2}|
+% \end{center}
+% \end{minipage}
+% \begin{minipage}{.34\textwidth}
+% \begin{equation*}
+%  \frac{1}{1 - x} = 1 + x + \orderof{x^2}
+% \end{equation*}
+% \end{minipage}
+%
+% It can also be used to discuss the growth of a function, e.g.
+% ``$\orderof{x^3}$ for large $x$,'' or for similar uses such as big-O notation
+% in computer algorithm analysis.
+%
+% \DescribeMacro{\sgn}
+% There is a macro for the sign operator, |\sgn|, defined as
+% \begin{equation*}
+%  \sgn x = \begin{cases}1 & x > 0 \\ 0 & x = 0 \\ -1 & x < 0\end{cases}
+% \end{equation*}
+% (and yes, this is not really \emph{complex} analysis)
+%
+% \DescribeMacro{\round}
+% Occasionally it's useful to have some way to designate rounding a number.
+% The |\round| macro can be used for that. It comes out as $\round(x)$ (I do
+% recommend the parentheses).
+%
+% \DescribeMacro{\evalat}
+% The macro
+% |\evalat|\marg{expression}\marg{lower limit}\marg{upper limit}
+% is mainly useful for when you want to denote the numerical value
+% of a derivative at a specific point, or when you want to represent the
+% evaluation of an integral at the endpoints of the range of integration.
+% It produces a vertical bar at the right of the \meta{expression},
+% with the \meta{lower limit} and \meta{upper limit} typeset at the
+% lower and upper endpoints of the bar, respectively.
+%
+% \begin{minipage}{.64\textwidth}
+% \begin{center}
+%  |\evalat{x^3 + 3x - 5}{2}{7}|
+% \end{center}
+% \end{minipage}
+% \begin{minipage}{.34\textwidth}
+% \begin{equation*}
+%  \evalat{x^3 + 3x - 5}{2}{7}
+% \end{equation*}
+% \end{minipage}
+%
+% \StopEventually{\PrintChanges\PrintIndex}
+%
+% \section{Feedback}
+%
+% This package is always a work in progress, both in terms of adding new macros
+% to the collection and fixing any errors or inconveniences in the ones that
+% are already here. Any feedback you may have will be welcome at my email address,
+% given at the top of the document.
+%
+% \section{Implementation}
+%
+% \subsection{Initialization}
+%    \begin{macrocode}
+\RequirePackage{ifthen}
+%    \end{macrocode}
+% This flag is set if the |particle| option is enabled. It enables definitions of particle symbol macros.
+%    \begin{macrocode}
+\newboolean{pparticle}
+%    \end{macrocode}
+% This flag is set if the |feynman| option is enabled. It pulls in the |feynmf| package.
+%    \begin{macrocode}
+\newboolean{pfeynman}
+%    \end{macrocode}

+%    \begin{macrocode}
+\newboolean{punits}
+%    \end{macrocode}
+% This flag is set if the |boldvectors| option is enabled. It causes vectors to be rendered using a bold font instead of an overset arrow.
+%    \begin{macrocode}
+\newboolean{pboldvectors}
+%    \end{macrocode}
+%
+% \subsection{Option Declarations}
+% These are the option declarations, pretty self-explanatory.
+%    \begin{macrocode}
+\DeclareOption{particle}{\setboolean{pparticle}{true}}
+\DeclareOption{units}{\setboolean{punits}{true}}
+\DeclareOption{feynman}{\setboolean{pfeynman}{true}}
+\DeclareOption{arrowvectors}{\setboolean{pboldvectors}{false}}
+\DeclareOption{boldvectors}{\setboolean{pboldvectors}{true}}
+\ProcessOptions\relax
+%    \end{macrocode}
+%
+% \subsection{Macro Definitions}
+% Here we bring in the AMS packages for mathematical notation.
+%    \begin{macrocode}
+\RequirePackage{amsbsy}
+\RequirePackage{amsmath}
+\RequirePackage{amsfonts}
+\RequirePackage{amssymb}
+\allowdisplaybreaks[2]
+\RequirePackage{accents}
+%    \end{macrocode}
+% |calligra| is the package that includes the script r, $\scriptr$.
+%    \begin{macrocode}
+\RequirePackage{calligra}
+\DeclareMathAlphabet{\mathcalligra}{T1}{calligra}{m}{n}
+\DeclareFontShape{T1}{calligra}{m}{n}{<->s*[2.2]callig15}{}
+\newcommand{\scriptr}{\mathcalligra{r}}
+%    \end{macrocode}
+% Scientific notation is implemented in the obvious way.
+%    \begin{macrocode}
+\newcommand{\sn}[2]{\ensuremath{#1\times10^{#2}}}
+%    \end{macrocode}
+% Here we load SIunits if the |units| option was passed.
+%    \begin{macrocode}
+\ifthenelse{\boolean{punits}}
+{
+ \RequirePackage[thinspace,mediumqspace,Gray,squaren]{SIunits}
+%    \end{macrocode}
+% These are some SI derived units that have been useful on occasion
+%    \begin{macrocode}
+ \addunit{\joulepercubicmeter}{\joule\per\cubic\meter}
+ \addunit{\joulepercubicmeterrp}{\joule\usk\rpcubic\meter}
+%    \end{macrocode}
+% These are some useful non-SI units, defined using the SIunits internal command |\addunits|
+%    \begin{macrocode}
+ \addunit{\torr}{torr}
+ \addunit{\mmhg}{mmHg}
+ \addunit{\amu}{amu}
+ \addunit{\yr}{yr}
+ \addunit{\erg}{erg}
+ \addunit{\gauss}{Ga}
+ \addunit{\molar}{M}
+ \addunit{\poise}{P}
+ \addunit{\foot}{ft}
+ \addunit{\mileperhour}{mph}
+ \addunit{\pound}{lb}
+%    \end{macrocode}
+% |\snunit| is implemented using a combination of |\sn| and |\unit|
+%    \begin{macrocode}
+ \newcommand{\snunit}[3]{\ifthenelse{\equal{#1}{1}}%
+  {\unit{10^{#2}}{#3}}{\unit{\sn{#1}{#2}}{#3}}}
+}
+{}
+%    \end{macrocode}
+% |\orderof| uses the calligraphic capital O, $\mathcal{O}$
+%    \begin{macrocode}
+\newcommand{\orderof}[1]{\ensuremath{\mathcal{O}\left(#1\right)}}
+%    \end{macrocode}
+% Now we come to assorted functions and keywords. First some inverse trig functions:
+%    \begin{macrocode}
+\DeclareMathOperator{\asin}{\sin^{-1}}
+\DeclareMathOperator{\acos}{\cos^{-1}}
+\DeclareMathOperator{\atan}{\tan^{-1}}
+\DeclareMathOperator{\asec}{\sec^{-1}}
+\DeclareMathOperator{\acsc}{\csc^{-1}}
+\DeclareMathOperator{\acot}{\cot^{-1}}
+%    \end{macrocode}
+% and hyperbolic trig functions:
+%    \begin{macrocode}
+\DeclareMathOperator{\sech}{sech}
+\DeclareMathOperator{\csch}{csch}
+\DeclareMathOperator{\asinh}{\sinh^{-1}}
+\DeclareMathOperator{\acosh}{\cosh^{-1}}
+\DeclareMathOperator{\atanh}{\tanh^{-1}}
+\DeclareMathOperator{\asech}{\sech^{-1}}
+\DeclareMathOperator{\acsch}{\csch^{-1}}
+\DeclareMathOperator{\acoth}{\coth^{-1}}
+%    \end{macrocode}
+% Next are some linear algebra keywords.
+%    \begin{macrocode}
+\DeclareMathOperator{\diag}{diag}
+\DeclareMathOperator{\realop}{Re}
+\DeclareMathOperator{\imagop}{Im}
+\newcommand{\real}[1]{\realop\{#1\}}
+\newcommand{\imag}[1]{\imagop\{#1\}}
+%    \end{macrocode}
+% The sign and absolute value keywords:
+%    \begin{macrocode}
+\DeclareMathOperator{\sgn}{sgn}
+\newcommand{\abs}[1]{\left\lvert#1\right\rvert}
+%    \end{macrocode}
+% Norm of a vector:
+%    \begin{macrocode}
+\newcommand{\norm}[1]{\left\lVert#1\right\rVert}
+%    \end{macrocode}
+% Evaluation at endpoints uses |\left.| to get no visible mark on the left side.
+%    \begin{macrocode}
+\newcommand{\evalat}[3]{\left.#1\right|_{#2}^{#3}}
+%    \end{macrocode}
+% Poisson brackets are just braces
+%    \begin{macrocode}
+\newcommand{\pbrac}[2]{\left\{#1,#2\right\}}
+\newcommand{\pbracvars}[4]{\left\{#1,#2\right\}_{#3,#4}}
+%    \end{macrocode}
+% This handles the redefinition of |\vec|. If the |boldvectors| option was passed,
+% a vector is denoted by bolding the argument. If |arrowvectors| was passed, the
+% vector is denoted by putting an arrow over the argument.
+% Some people use an undertilde, which will probably be added in the future.
+%    \begin{macrocode}
+\ifthenelse{\boolean{pboldvectors}}%
+ {\renewcommand{\vec}[1]{\mathbf{#1}}}%
+ {\renewcommand{\vec}[1]{\accentset{\rightharpoonup}{#1}}}
+%    \end{macrocode}
+% |\vecvar| is just a synonym for |\vec|
+%    \begin{macrocode}
+\newcommand{\vecvar}[1]{\vec{#1}}
+%    \end{macrocode}
+% |\tnsvar| always uses bold. Some people use undertildes, which will be added.
+%    \begin{macrocode}
+\newcommand{\tnsvar}[1]{\mathbf{#1}}
+%    \end{macrocode}
+% |\matvar| always uses bold.
+%    \begin{macrocode}
+\newcommand{\matvar}[1]{\mathbf{#1}}
+%    \end{macrocode}
+% |\identitym| is a bold $1$
+%    \begin{macrocode}
+\newcommand{\identitym}{\mathbf{1}}
+%    \end{macrocode}
+% |\determinant| uses vertical bars.
+%    \begin{macrocode}
+\newcommand{\determinant}[1]{\left\lvert#1\right\rvert}
+%    \end{macrocode}
+% |\trace| uses capital Tr.
+%    \begin{macrocode}
+\DeclareMathOperator{\trace}{Tr}
+%    \end{macrocode}
+% Now we get to some unit vectors, all just the relevant letter with a hat.
+%    \begin{macrocode}
+\newcommand{\unitd}{\hat{d}}
+\newcommand{\unite}{\hat{e}}
+\newcommand{\uniti}{\hat{i}}
+\newcommand{\unitj}{\hat{j}}
+\newcommand{\unitk}{\hat{k}}
+\newcommand{\unitl}{\hat{\ell}}
+\newcommand{\unitn}{\hat{n}}
+\newcommand{\unitp}{\hat{p}}
+\newcommand{\unitq}{\hat{q}}
+\newcommand{\unitr}{\hat{r}}
+\newcommand{\units}{\hat{s}}
+\newcommand{\unitt}{\hat{t}}
+\newcommand{\unitu}{\hat{u}}
+\newcommand{\unitv}{\hat{v}}
+\newcommand{\unitw}{\hat{w}}
+\newcommand{\unitx}{\hat{x}}
+\newcommand{\unity}{\hat{y}}
+\newcommand{\unitz}{\hat{z}}
+\newcommand{\unitphi}{\hat{\phi}}
+\newcommand{\unitrho}{\hat{\rho}}
+\newcommand{\unittheta}{\hat{\theta}}
+\newcommand{\unitomega}{\hat{\omega}}
+%    \end{macrocode}
+% This turns any letter into a unit vector.
+%    \begin{macrocode}
+\newcommand{\unitvec}[1]{\hat{#1}}
+%    \end{macrocode}
+% |\udc| is just an upright (roman) d, and similarly for higher-order differentials.
+%    \begin{macrocode}
+\newcommand{\udc}{\mathrm{d}}
+\newcommand{\uddc}{\mathrm{d}^2}
+\newcommand{\udddc}{\mathrm{d}^3}
+%    \end{macrocode}
+% |\pdc| is just |\partial|, defined for similarity with |\udc|.
+%    \begin{macrocode}
+\newcommand{\pdc}{\partial}
+\newcommand{\pddc}{\partial^2}
+\newcommand{\pdddc}{\partial^3}
+%    \end{macrocode}
+% |\uds| is just like |\udc| but it includes a small space in front. If I can figure
+% out how to do it I'll make the command autodetect the preceding character(s) and
+% figure out whether to add the space or not.
+%    \begin{macrocode}
+\newcommand{\uds}{\,\mathrm{d}}
+\newcommand{\udds}{\,\mathrm{d}^2}
+\newcommand{\uddds}{\,\mathrm{d}^3}
+%    \end{macrocode}
+% |\pds| is also defined for similarity as just |\partial| with a space in front,
+% although I'm not sure this one is really useful.
+%    \begin{macrocode}
+\newcommand{\pds}{\,\partial}
+\newcommand{\pdds}{\,\partial^2}
+\newcommand{\pddds}{\,\partial^3}
+%    \end{macrocode}
+% |\ud| typesets a derivative using |\udc|. Similarly for second and third derivatives.
+%    \begin{macrocode}
+\newcommand{\ud}[2]{\frac{\mathrm{d}#1}{\mathrm{d}#2}}
+\newcommand{\udd}[2]{\frac{\mathrm{d}^2#1}{\mathrm{d} #2^2}}
+\newcommand{\uddd}[2]{\frac{\mathrm{d}^3#1}{\mathrm{d} #2^3}}
+%    \end{macrocode}
+% |\pd| does the same for partial derivatives with |\pdc|.
+%    \begin{macrocode}
+\newcommand{\pd}[2]{\frac{\partial #1}{\partial #2}}
+\newcommand{\pdd}[2]{\frac{\partial^2#1}{\partial #2^2}}
+\newcommand{\pddd}[2]{\frac{\partial^3#1}{\partial #2^3}}
+%    \end{macrocode}
+% |\grad| typesets the gradient symbol, a nabla with an arrow over it (actually a harpoon).
+% This is done the same way regardless of the |arrowvectors| or |boldvectors| setting.
+%    \begin{macrocode}
+\newcommand{\grad}{\accentset{\rightharpoonup}{\nabla}}
+%    \end{macrocode}
+% |\div| is the divergence, defined using |\grad|. Ordinarily |\div| stands for the
+% division symbol but nobody really uses that, so I figured it's worth replacing.
+%    \begin{macrocode}
+\renewcommand{\div}{\grad\cdot}
+%    \end{macrocode}
+% |\curl| is done in the obvious way using |\grad|
+%    \begin{macrocode}
+\newcommand{\curl}{\grad\times}
+%    \end{macrocode}
+% |\lapl| is written without a harpoon since it's a scalar operator
+%    \begin{macrocode}
+\newcommand{\lapl}{\nabla^2}
+%    \end{macrocode}
+% |\conj| just puts a superscript star
+%    \begin{macrocode}
+\newcommand{\conj}[1]{{#1 ^{*}}}
+%    \end{macrocode}
+% |\herm| is the same thing but for operators or matrices, so with a dagger
+%    \begin{macrocode}
+\newcommand{\herm}[1]{{#1 ^{\dagger}}}
+%    \end{macrocode}
+% |\transpose| does the same with a $T$
+%    \begin{macrocode}
+\newcommand{\transpose}[1]{{#1 ^{T}}}
+%    \end{macrocode}
+% These set notations are mostly done with |\mathbb|
+%    \begin{macrocode}
+\newcommand{\natset}{\mathbb{N}}
+\newcommand{\intset}{\mathbb{Z}}
+\newcommand{\cpxset}{\mathbb{C}}
+\newcommand{\whlset}{\mathbb{Q}}
+\newcommand{\realset}{\mathbb{R}}
+\newcommand{\imagset}{\mathbb{I}}
+%    \end{macrocode}
+% Now Dirac notation, implemented using vertical bars and angle brackets in various combinations
+%    \begin{macrocode}
+\newcommand{\bra}[1]{\left\langle #1 \right\rvert}
+\newcommand{\ket}[1]{\left\lvert #1 \right\rangle}
+\newcommand{\braket}[2]{\langle #1 \vert #2 \rangle}
+\newcommand{\melement}[3]{\langle #1 \vert #2 \vert #3 \rangle}
+\newcommand{\projop}[2]{\vert #1 \rangle #2 \langle #1 \vert}
+\newcommand{\expect}[1]{\left\langle #1 \right\rangle}
+%    \end{macrocode}
+% Commutators and anticommutators are done in the obvious way
+%    \begin{macrocode}
+\newcommand{\commut}[2]{\left[ #1, #2 \right]}
+\newcommand{\acommut}[2]{\left\{ #1, #2 \right\}}
+%    \end{macrocode}
+% The |\round| operator just typesets the word ``round''
+%    \begin{macrocode}
+\DeclareMathOperator{\round}{round}
+%    \end{macrocode}
+% The exterior derivative is typeset in bold, in contrast to the differential $\udc$ which
+% is just a plain roman font
+%    \begin{macrocode}
+\DeclareMathOperator{\exd}{\mathbf{d}}
+%    \end{macrocode}
+% The Hodge dual uses a star, but not superscript like |\conj|.
+%    \begin{macrocode}
+\newcommand{\hodge}{\star}
+%    \end{macrocode}
+% These are short macros to typeset the symbols for the elementary (and common non-elementary)
+% particles. Each one is set in math roman font, as opposed to text roman font if it makes
+% a difference. They're followed by an empty token |{}| for reasons which I forget.
+%
+% Theoretically these should only be loaded if the |particle| option was passed but I'll get
+% to that later; in the meantime they're unlikely to conflict with anything important.
