+The mandi package provides commands for typesetting symbols, expressions, and
+quantities used in introductory physics and astronomy. Many of the commands are
+inspired by Matter & Interactions by Ruth Chabay and Bruce Sherwood. Many of
+the astronomical commands were inspired by my own classroom needs. It must be
+understood that mandi does not do any computations! It only provides commands
+for typesetting.
+
+Run the file mandi.dtx through (pdf)LaTeX to generate README (this file),
+mandi.ins, mandi.sty, vdemo.py, and mandi.pdf (user documentation). I assume
+a TeXLive2011 or later distribution is installed.

+%
+% \section{Introduction}
+% This package provides a collection of commands useful in introductory physics
+% and astronomy. The underlying philosophy is that the user, potentially an
+% introductory student, should just type the name of a physical quantity, with a
+% numerical value if needed, without having to think about the units. \mandi\
+% will typeset everything correctly. For symbolic quantities, the user should
+% type only what is necessary to get the desired result. What one types should
+% correspond as closely as possible to what one thinks when writing. The package
+% name derives from \mi
+% \footnote{See the \mi\ home page at \url{http://www.matterandinteractions.org/}
+% for more information about this innovative introductory calculus-based physics
+% curriculum.} by Ruth Chabay and Bruce Sherwood. The package certainly is rather
+% tightly tied to that textbook but can be used for typesetting any document that
+% requires consistent physics notation. With \mandi\ many complicated expressions
+% can be typeset with just a single command. Great thought has been given to command
+% names and I hope users find the conventions logical and easy to remember.\medskip
+%
+% There are other underlying philosophies and goals embedded within \mandi, all of
+% which are summarized here. They are
+% \begin{itemize}
+% \item to employ a \textit{type what you think} model for remembering commands
+% \item to relieve the user of having to explicitly worry about typesetting SI units
+% \item to enforce certain concepts that are too frequently merged, which causes
+% confusion, such as the distinction between a vector quantity and its magnitude
+% (e.g.\ we often use the same name for both)
+% \item to enforce consistent terminology in the naming of quantities, with names
+% that are both meaningful to introductory students and accurate
+% (e.g.\ \textit{duration} vs.\ \textit{time})
+% \item to enforce consistent notation, especially for vector quantities
+% \end{itemize}
+%
+% I hope that using \mandi\ will cause users to form good habits that benefit
+% physics students.
+%
+% \section{Building From Source}
+% I am assuming the user will use pdf\LaTeX, which creates PDF files as output, to
+% build the documentation. I have not tested the build with with standard \LaTeX,
+% which creates DVI files.
+%
+% \newpage
+% \section{Loading the Package}
+% To load the \mandi\ package, simply put the line \medskip
+%
+% |\usepackage{mandi}| \medskip
+%
+% \noindent in your document's preamble to load \mandi\ with its default
+% options. To use the package's available options, write \medskip
+%
+% |\usepackage|\textbf{[}\opt{options}\textbf{]}|{mandi}| \medskip
+%
+% There are five available options, with one option being based on the absence of two
+% of the others.
+% \begin{itemize}
+% \item \opt{italicvectors} gives italic letters for the kernels of vector
+% names. Otherwise, the letters are in Roman.
+% \item \opt{doubleabsbars} gives double bars in symbols for vector magnitudes.
+% Otherwise, single bars are used. Double bars may be more familiar to
+% students from their calculus courses.
+% \item \opt{baseunits} causes all units to be displayed in \baseunits\ form, with
+% SI base units. No solidi (slashes) are used. Positive and negative exponents
+% are used to denote powers of various base units.
+% \item \opt{drvdunits} causes all units to be displayed, when possible, in
+% \drvdunits\ form, with SI derived units. Students may already be familiar with
+% many of these derived units.
+% \item If neither \opt{baseunits} nor \opt{drvdunits} is specified (the
+% default), units are displayed in what I call \tradunits\ form, which
+% is typically the way they would traditionally appear in textbooks. Units in this
+% form frequently hide the underlying physical meaning and are probably not best
+% pedagogically but are familiar to students and teachers. In this document, the
+% default is to use
+% \ifthenelse{\boolean{@optbaseunits}}
+% {base}
+% {\ifthenelse{\boolean{@optdrvdunits}}
+% {derived}
+% {traditional}}
+% units. As you will see later, there are ways to override these options either
+% temporarily or permanently.
+% \end{itemize}
+%
+% \newpage
+% \section{Usage}
+% So what does \mandi\ allow you to do? Suppose you want to typeset a calculation of
+% a particle's kinetic energy (assume the magnitude of the particle's velocity is much
+% less than the magnitude of light's velocity). You could use
+%
+% \begin{center}
+% |K \approx \frac{1}{2}\left(\unit{2}{\kg}\right)\left(\unit{2}{\m\per\s}\right)^2|
+% \end{center}
+%
+% but it is more logical and more readable to use
+%
+% \begin{center}
+% |K \approx \onehalf (\mass{2})(\velocity{2})^2|
+% \end{center}
+%
+% given that they produce the same output. The second way is what \mandi\ lets you do.
+%
+% \[ K \approx \onehalf (\mass{2})(\velocity{2})^2 \]
+%
+% The second way is more readable if you come back to the document, perhaps having
+% not looked at the source code for a while. Suppose you want to use vectors quantities.
+% That's no problem because \mandi\ handles vector quantities.
+%
+% \begin{center}
+% |Calculate the magnitude of \momentum{\mivector{3,2,5}}.|
+% \end{center}
+%
+% produces
+%
+% \begin{center}
+% Calculate the magnitude of \momentum{\mivector{3,2,5}}.
+% \end{center}
+%
+% The underlying strategy is to \textit{think about how you would say what you want
+% to write and then write it the way you would say it}. With a few exceptions, this
+% is how \mandi\ works. You need not worry about units because \mandi\ knows what
+% SI units go with which physical quantities. You can define new quantities so that
+% \mandi\ knows about them and in doing so, you give the new quantities the same
+% names they would normally have.
+%
+% If you want to save time in writing out the energy principle, just use
+%
+% \begin{center}
+% |\energyprinciple|
+% \end{center}
+%
+% which gives
+%
+% \[
+% \energyprinciple
+% \]
+%
+% with fewer keystrokes, and it's easier to remember.
+%
+% This barely scratches the surface in describing \mandi\ so continue reading this
+% document to see everything this package can do.
+%
+% \newpage
+% \section{Features and Commands}
+% \subsection{Autosized Parentheses}
+% An experimental feature of \mandi\ is autosized parentheses in math mode. This means
+% you need never use |\left(| or |\right)|. Just use unadorned parentheses and they will
+% size correctly. Note that this only works in math mode, only works for parentheses and
+% not for other delimiters.
+%
+% To illustrate, |(\oofpezmathsymbol)| gives (\oofpezmathsymbol) but
+% |\((\oofpezmathsymbol)\)| gives \((\oofpezmathsymbol)\).
+%
+% \subsection{SI Base Units}
+% This is not a tutorial on SI units and the user is assumed to be familiar with SI
+% rules and usage. Begin by defining shortcuts for the units for the seven SI base
+% quantities:
+% \textit{spatial displacement} (what others call \textit{length}), \textit{mass},
+% \textit{temporal displacement} (what others call \textit{time}, but we will call
+% it \textit{duration} in most cases), \textit{electric current}, \textit
+% {thermodynamic temperature}, \textit{amount}, and \textit{luminous intensity}.
+% These shortcuts are used internally and need not explicitly be invoked by the
+% user.\medskip

+%
+% If \mandi\ was invoked with \opt{baseunits}, then every physical
+% quantity will have a unit that is some product of powers of these seven base SI
+% units. Exceptions are angular quantities, which will include either degrees or
+% radians depending upon the application. Again, this is what we mean by
+% \baseunits\ form.\medskip
+%
+% Certain combinations of the SI base units have nicknames and each such
+% combination and nickname constitutes a \textit{derived unit}. Derived units are
+% no more physically meaningful than the base units, they are merely nicknames for
+% particular combinations of base units. An example of a derived unit is the
+% newton, for which the symbol (it is not an abbreviation) is \newton. However,
+% the symbol \newton\ is merely a nickname for a particular combination of base
+% units, specifically \newtonbase. It is not the case that every unique combination
+% of base units has a nickname, but those that do are usually named in honor of a
+% scientist. Incidentally, in such cases, the symbol is capitalized but the
+% \textit{name} of the unit is \textbf{never} capitalized. Thus we would write the
+% name of the derived unit of force as newton and not Newton. Again, using these
+% select nicknames for certain combinations of base units is what we mean by
+% \drvdunits\ form.
+%
+% \newpage
+% \subsection{Defining Physics Quantities}
+%

+%</example>
+%\fi
+%
+% Using this command causes several things to happen.
+% \begin{itemize}
+% \item A command |\yournewquantity|\marg{magnitude}, where |foobar| is the first
+% argument passed to \\
+% |\newphysicsquantity|, is created that takes one mandatory
+% argument, a numerical magnitude. Subsequent use of your defined scalar quantity
+% can be invoked by typing \\ |\yournewquantity|\marg{magnitude} and the units will be
+% typeset according to the options given when \mandi\ was loaded. Note that if the
+% \drvdunits\ and \tradunits\ forms are not specified, they will be
+% populated with the \baseunits\ form.
+% \item A command |\yournewquantitybaseunit|\marg{magnitude} is created that expresses
+% the quantity and its units in \baseunits\ form.
+% \item A command |\yournewquantitydrvdunit|\marg{magnitude} is created that expresses
+% the quantity and its units in \drvdunits\ form. This command is created whether
+% or not the first optional argument is provided.
+% \item A command |\yournewquantitytradunit|\marg{magnitude} is created that
+% expresses the quantity and its units in \tradunits\ form. This command is
+% created whether or not the first optional argument is provided.
+% \item A command |\yournewquantityonlybaseunit|\marg{magnitude} is created that
+% expresses
+% \textbf{only} the quantity's units in \baseunits\ form.
+% \item A command |\yournewquantityonlydrvdunit|\marg{magnitude} is created that
+% expresses \textbf{only} the quantity's units in \drvdunits\ form.
+% \item A command |\yournewquantityonlytradunit|\marg{magnitude} is created that
+% expresses \textbf{only} the quantity's units in \tradunits\ form.
+% \item A command |\yournewquantityvalue|\marg{magnitude} is created that expresses
+% \textbf{only} the quantity's numerical value.
+% \end{itemize}
+%
+% The following command defines the quantity |\displacement| and its
+% associated commands containing its units.
+% \begin{quotation}
+% \begin{tabular}{l}
+% |\newphysicsquantity{displacement}{\m}[\m][\m]|
+% \end{tabular}
+% \end{quotation}
+%
+% You would then invoke this quantity with |\displacement{3}|
+% to get \displacement{3} in a calculation.
+%
+% \subsubsection{Defining Vector Quantities}
+%
+% Vector quantities are defined exactly like other quantities, except a formatted
+% vector is used when invoking the value of that quantity. The following command defines
+% a vector |\displacementvector| and its associated commands containing its units.
+%
+% \begin{quotation}
+% \begin{tabular}{l}
+% |\newphysicsquantity{displacementvector}{\m}[\m][\m]|
+% \end{tabular}
+% \end{quotation}
+%
+% \newphysicsquantity{displacementvector}{\m}[\m][\m]
+%
+% You would then invoke this quantity with |\displacementvector{\mivector{2,3,-5}}|
+% to get \displacementvector{\mivector{2,3,-5}} in a calculation.
+%
+% \subsection{First Semester Physics}
+% The first semester of \mi\ focuses on mechanics, dynamics, and statistical mechanics.
+%
+% \subsubsection{Predefined Quantities}
+%
+% The seven fundamental quantities are similarly defined and examples of their
+% usage is given in the following table.
+%
+% \begin{center}
+% \begin{tabular}{c c}
+% |\displacement{3.14}| & \displacement{3.14} \\
+% |\mass{2.81}| & \mass{2.81} \\
+% |\duration{4.32}| & \duration{4.32} \\
+% |\current{5.19}| & \current{5.19} \\
+% |\temperature{273}| & \temperature{273} \\
+% |\amount{2.87}| & \amount{2.87} \\
+% |\luminous{5.64}| & \luminous{5.64} \\
+% \end{tabular}
+% \end{center}
+%
+% Okay, so much for the base quantities. While we're at it, let's also go ahead and
+% define plane angle, solid angle, and a few non-SI units of angular measure, energy,
+% and distance.
+%
+% \begin{center}
+% \begin{tabular}{c c}
+% |\planeangle{2.88}| & \planeangle{2.88} \\
+% |\solidangle{4\pi}| & \solidangle{4\pi} \\
+% |\indegrees{30.1}| & \indegrees{30.1} \\
+% |\inarcminutes{30.1}| & \inarcminutes{30.1} \\
+% |\inarcseconds{30.1}| & \inarcseconds{30.1} \\
+% |\ineV{10.2}| & \ineV{10.2} \\
+% |\inAU{5.2}| & \inAU{5.2}
+% \end{tabular}
+% \end{center}
+%
+% Angles are confusing in introductory physics because sometimes we write the unit
+% and sometimes we do not. Some concepts, such as flux, are simplified by
+% introducing solid angle.\medskip
+%
+% Now let us move on into first semester physics, defining quantities in the approximate
+% order in which they appear in \mi. Use |\scin[]{}| to get
+% scientific notation, with the mantissa as the optional first argument and the exponent
+% as the required second argument. An optional third argument specifies a unit, but that
+% is not needed in the following examples.
+%
+% \begin{center}
+% \begin{tabular}{c c}
+% |\velocityc{0.24}| & \velocityc{0.24} \\
+% |\velocity{2.99}| & \velocity{2.99} \\
+% |\gamman{4.32}| & \gamman{4.32} \\
+% |\momentum{\scin[2.44]{4}}| & \momentum{\scin[2.44]{4}} \\
+% |\acceleration{9.81}| & \acceleration{9.81} \\
+% |\impulse{3.56}| & \impulse{3.56} \\
+% |\force{2.84}| & \force{2.84} \\
+% |\springstiffness{6.92}| & \springstiffness{6.92} \\
+% |\springstretch{0.212}| & \springstretch{0.212} \\
+% |\area{0.125}| & \area{0.125} \\
+% |\volume{5.33}| & \volume{5.33} \\
+% |\linearmassdensity{2.33}| & \linearmassdensity{2.33} \\
+% |\areamassdensity{3.60}| & \areamassdensity{3.60} \\
+% |\volumemassdensity{27.4}| & \volumemassdensity{27.4} \\
+% |\youngsmodulus{\scin[2.12]{9}}| & \youngsmodulus{\scin[2.12]{9}} \\
+% |\work{4.04}| & \work{4.04} \\
+% |\energy{4.40}| & \energy{4.40} \\
+% |\power{100.2}| & \power{100.2} \\
+% |\angularvelocity{3.02}| & \angularvelocity{3.02} \\
+% |\angularacceleration{5.32}| & \angularacceleration{5.32} \\
+% |\angularmomentum{6.81}| & \angularmomentum{6.81} \\
+% |\momentofinertia{4.59}| & \momentofinertia{4.59} \\
+% |\torque{3.40}| & \torque{3.40} \\
+% |\entropy{5.95}| & \entropy{5.95} \\
+% |\wavelength{\scin[4.00]{-7}}| & \wavelength{\scin[4.00]{-7}} \\
+% |\wavenumber{\scin[2.50]{6}}| & \wavenumber{\scin[2.50]{6}} \\
+% |\frequency{\scin[7.50]{14}}| & \frequency{\scin[7.50]{14}} \\
+% |\angularfrequency{\scin[4.70]{15}}| & \angularfrequency{\scin[4.70]{15}}
+% \end{tabular}
+% \end{center}
+%
+% Two quick thoughts here. First, work and energy are similar to momentum and impulse
+% in that they come from two different concepts. Work comes from force acting through
+% a spatial displacement and energy is a fundamental property of matter. It is a
+% coincidence that they have the same dimensions and thus the same unit. Second, notice
+% that I didn't define speed. Velocity is the only quantity I can think of for which we
+% have different names for the vector and the magnitude of the vector. I decided to put
+% it on the same footing as momentum, acceleration, and force.
+%
+% \newpage
+% \subsection{Second Semester Physics}
+% The second semester of \mi\ focuses on electromagnetic theory, and there are many
+% primary and secondary quantities.
+%
+% \subsubsection{Predefined Quantities}
+%
+% \begin{center}
+% \begin{tabular}{c c}
+% |\charge{\scin[2]{-9}}| & \charge{\scin[2]{-9}} \\
+% |\permittivity{\scin[9]{-12}}| & \permittivity{\scin[9]{-12}} \\
+% |\electricfield{\scin[2]{5}}| & \electricfield{\scin[2]{5}} \\
+% |\electricdipolemom{\scin[3]{-22}}| & \electricdipolemom{\scin[3]{-22}} \\
+% |\permeability{\scin[4\pi]{-7}}| & \permeability{\scin[4\pi]{-7}} \\
+% |\magneticfield{1.25}| & \magneticfield{1.25} \\
+% |\cmagneticfield{1.25}| & \cmagneticfield{1.25}
+% \end{tabular}
+% \end{center}
+%
+% \newpage
+% \subsection{Further Words on Units}
+% As you recall, when a new scalar or vector is defined, a host of other commands
+% is also automatically defined. Consider momentum. The following commands are
+% defined:
+%
+% \begin{quotation}
+% \begin{tabular}{c c c}
+% |\momentum{3}| & \momentum{3} & unit determined by global options\\
+% |\momentumbaseunit{3}| & \momentumbaseunit{3} & quantity with base unit \\
+% |\momentumdrvdunit{3}| & \momentumdrvdunit{3} & quantity with derived unit \\
+% |\momentumtradunit{3}| & \momentumtradunit{3} & quantity with traditional unit \\
+% |\momentumvalue{3}| & \momentumvalue{3} & numerical value of quantity \\
+% |\momentumonlybaseunit| & \momentumonlybaseunit & selects only base unit \\
+% |\momentumonlydrvdunit| & \momentumonlydrvdunit & selects only derived unit \\
+% |\momentumonlytradunit| & \momentumonlytradunit & selects only traditional unit
+% \end{tabular}
+% \end{quotation}
+%
+% The form of a quantity's unit can be changed on the fly regardless of the global
+% format determined by \opt{baseunits} and \opt{drvdunits}. One way, as illustrated
+% in the table above, is to append |baseunit|, |drvdunit|, |tradunit| to the
+% quantity's name, and this will override the global options for that instance.
+%
+% \DescribeMacro{\hereusebaseunit}
+% \DescribeMacro{\hereusedrvdunit}
+% \DescribeMacro{\hereusetradunit}
+% A second way is to use the commands |\hereusebaseunit{}|, |\hereusedrvdunit{}|, or
+% |\hereusetradunit{}| with the quantity as the argument.
+%
+% \begin{quotation}
+% \begin{tabular}{c c}
+% |\hereusebaseunit{\momentum{3}}| & \hereusebaseunit{\momentum{3}} \\
+% |\hereusedrvdunit{\momentum{3}}| & \hereusedrvdunit{\momentum{3}} \\
+% |\hereusetradunit{\momentum{3}}| & \hereusetradunit{\momentum{3}}
+% \end{tabular}
+% \end{quotation}
+%
+% \DescribeEnv{usebaseunit}
+% \DescribeEnv{usedrvdunit}
+% \DescribeEnv{usetradunit}
+% A third way is to use the |usebaseunit|, |usedrvdunit|, |usetradunit|
+% environments. \\
+%
+% \begin{quotation}
+% \begin{tabular}{c c}
+% |\begin{usebaseunit}| & \\
+% | \momentum{3} | & \begin{usebaseunit}\momentum{3}\end{usebaseunit}\\
+% |\end{usebaseunit} | & \\
+% |\begin{usedrvdunit}| & \\
+% | \momentum{3} | & \begin{usedrvdunit}\momentum{3}\end{usedrvdunit}\\
+% |\end{usedrvdunit} | & \\
+% |\begin{usetradunit}| & \\
+% | \momentum{3} | & \begin{usetradunit}\momentum{3}\end{usetradunit}\\
+% |\end{usetradunit} | & \\
+% \end{tabular}
+% \end{quotation}
+%
+% \DescribeMacro{\perpusebaseunit}
+% \DescribeMacro{\perpusedrvdunit}
+% \DescribeMacro{\perpusetradunit}
+% A fourth way is to use the global switches |\perpusebaseunit|, |\perpusedrvdunit|,
+% and \\
+% |\perpusetradunit| (think \textit{perpetually use\ldots}). \textbf{It's important to
+% remember that these switches override the global options for the rest of the document
+% or until overridden by one of the other two switches.}

+% \subsubsection{Naming Conventions You Have Seen}
+% By now you probably understand that commands are named as closely as possible
+% to the way you would say or write what you want. Every time you see |comp|
+% you should think of a single component. Every time you see |scomps| you should
+% think of a set of symbolic components. Every time you see |der| you should
+% think derivative. Every time you see |dir| you should think direction. I have
+% tried to make the names simple both logically and lexically. \\
+%
+% \newpage
+% \subsubsection{Subscripted Vectors}
+% Now we have commands for vectors that carry subscripts, usually to identify an
+% object or something similar. Basically, |vect| becomes |vectsub| and |pos|
+% becomes |possub|. Ideally, a subscript should not contain mathematical
+% symbols. However, if you wish to do so, just wrap the symbol with
+% |\(|\(\ldots \)|\)| as you normally would. All of the commands for non-subscripted
+% vectors are available for subscripted vectors. \\

+% new ones though. Every time you see |dot| you should think \textit{dot product}.
+% When you see |dots| you should think \textit{dot product in terms of symbolic
+% components}. When you see |dote| you should think \textit{dot product
+% expanded as a sum}. These, along with the previous naming conventions, handle
+% many dot product expressions. \\
