-BXcalc Package
-==============
-
-LaTeX: To extend the functionality of the calc package
-
-This package bundle consists of the following packages:
-
- * bxcalcize: To make calc expressions available in more places.
-
- * bxcalcux: To add user-defined units to the calc syntax.
-
-In addition, this bundle provides the bxcalc package, which simply loads
-the above-mentioned packages internally.
-
-### System requirement
-
- * TeX format: LaTeX.
- * TeX engine: Anything.
- - Some functions requires the e-TeX extension.
- * Dependent packages:
- - calc
-
-### Installation
-
- - `*.sty` → $TEXMF/tex/latex/BXcalc
-
-### License
-
-This package is distributed under the MIT License.
-
-bxcalc package ― main
-----------------------
-
-This package simply loads all other packages in this bundle.
-
-Note: Under the LaTeX kernel of the version 2020/10/01 or later, the
-bxcalcize package is not loaded since it is no longer needed.
-
-
-bxcalcize package ― to make calc expressions available in more places
-----------------------------------------------------------------------
-
-Some standard LaTeX commands involving length specification do not allow
-the use of calc expressions. This package makes such uses possible.
-
-See the manual bxcalcize.pdf for detail.
-
-Note: The functionality of this package will be provided by the LaTeX
-kernel of the version 2020/10/01.
-
-
-bxcalcux package ― to add user-defined units to the calc syntax
-----------------------------------------------------------------
-
-This package enables users to define new length units and use them in
-calc expressions.
-
-See the manual bxcalcux.pdf for detail.
-
-
-Revision History
-----------------
-
- * Version 1.1 〈2020/09/25〉
- - Support LaTeX kernel 2020/10/01.
-
- * Version 1.0b 〈2019/11/24〉
- - Bug fix.
-
- * Version 1.0a 〈2018/01/28〉
- - Bug fix.
-
- * Version 1.0 〈2017/05/21〉
- - The first public version as this bundle, which has been seperated
- from the old BXjatool bundle.

-\maketitle
-
-%===========================================================
-\section{Notice}
-
-Functionality of this package will be provided by the LaTeX
-kernel of the version 2020/10/01.
-
-%===========================================================
-\section{Overview}
-
-After loading \Pkg{calc}, most of the length specifications
-in {\LaTeX} become aware of that package--- i.e.\
-\Pkg{calc} expressions can be written in place of
-simple lengths.
-However some commands remain \Pkg{calc}-unaware; for example
-one cannot use expressions in the argument of |\hspace|.
-This package patches to the {\LaTeX} kernel and eliminates
-remaining \Pkg{calc}-unawareness
-(as far as I know).
-
-\paragraph{Supported format} \LaTeX.
-\paragraph{Supported engine} Any engine with {\eTeX} extensions.
-\paragraph{Prerequisite packages} \Pkg{calc} package.
-
-%===========================================================
-\section{Package Loading}
-
-Use |\usepackage| as usual, with no options.
-\begin{quote}\small\begin{verbatim}
-\usepackage{bxcalcize}
-\end{verbatim}\end{quote}
-
-%===========================================================
-\section{Usage}
-
-After loading the package, one can use \Pkg{calc} expressions
-in the following places:
-\begin{itemize}
-\item the sole argument of |\hspace|(|*|), |\vspace|(|*|),
-and |\addvspace|;
-\item the sole optional argument of |\\|.
-\end{itemize}

-%===========================================================
-\section{Overview}
-
-This package allows one to create a new unit of length
-that can be used in length expressions
-of the \Pkg{calc} package.
-For example,
-\begin{quote}\small\begin{verbatim}
-\newcalcunit{thou}{0.07227pt}% thousandth of inch
-\setlength{\lengthA}{10thou}
-\end{verbatim}\end{quote}
-will assign 0.72266\,pt to |\lengthA|.%
-\footnote{Using \texttt{0.001in} instead of
-\texttt{0.07227pt} will give rather inaccurate results,
-since \texttt{0.001in} is evaluated to 0.7277\,pt.}
-
-\paragraph{Supported format} \LaTeX.
-\paragraph{Supported engine} Any engine with {\eTeX} extension.
-\paragraph{Prerequisite packages}
-\Pkg{calc}, \Pkg{etoolbox}.
-
-%===========================================================
-\section{Package Loading}
-
-Use |\usepackage| as usual, with no options.
-\begin{quote}\small\begin{verbatim}
-\usepackage{bxcalcux}
-\end{verbatim}\end{quote}
-
-%===========================================================
-\section{Usage}
-
-\begin{itemize}
-\item |\newcalcunit{|\Meta{unit}|}{|\Meta{length}|}|\Means
-Declares a new unit \Meta{unit} as equal to \Meta{length}.
-The unit name must consist only of alphabets.
-You can use relative units such as |0.5em| in \Meta{length},
-and such relative units are resolved
-when \Pkg{calc} expressions are evaluated.
-
-\item |\DeclareCalcUnit{|\Meta{unit}|}{|\Meta{text}|}|\Means
-\textsl{(for {\TeX}nicians)}
-Declares a new unit \Meta{unit} as equal to the unit
-expressed by a token list \Meta{text},
-which must form a ``unit of dimen'' (in {\TeX} terminology).
-Here is an example.
-\begin{quote}\small\begin{verbatim}
-\DeclareCalcUnit{ls}{\baselineskip}% current line skip
-\end{verbatim}\end{quote}
-
-\end{itemize}
-
-%===========================================================
-\section{Notices}
-
-\begin{itemize}
-\item Usually unit names are treated as case-insensitive;
-but as exception, unit names with a single letter are
-case-sensitive.
-\item You must not create a unit name that coincides
-with a prefix of existing (built-in or created) units
-or any keywords that could be used in \Pkg{calc} expressions
-(such as |plus|, |fil|, etc.); otherwise unexpected
-things would occur.
-\end{itemize}
