+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.
+
+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.
+
+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 1.0 〈2017/05/21〉
+ - The first public version as this bundle, which has been seperated
+ from the old BXjatool bundle.

+\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).
+

+\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 |\\|.

+%===========================================================
+\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}
