+The ESRELATION package
+======================
+by Byron Cook, Tauba Auerbach, David Reinfurt
+
+About
+-----
+
+The program termination problem, also known at the uniform halting problem, can be defined as: *Using a finite amount of time: determine whether a given program will always finish running or could possibly execute forever.*
+
+The Metafont programming and LaTeX package writing and TeX macro programming (*especially the TeX macro programming*) required to produce these symbols looked like it might, itself, never end. It took more than a year of work in fits and starts to understand how the jalopy of bits and pieces go together to make a font work with LaTeX. [The Comprehensive LaTeXe Symbol List](http://www.ctan.org/tex-archive/info/symbols/comprehensive/ "CTAN") does not currently include this set, but on completion all of these files will be ready to upload in the correct formats for inclusion. These are implemented as a standard TeX math symbol font, implemented with custom Metafont sources, rendered on-the-fly as needed by LaTeX. Also provided in this package is a PostScript Type-1 version of the font. Symbols are accessed through macros defined in this package.
+
+Installation
+------------
+
++ run latex on esrelation.ins to generate sty, mf, fd files
+ > $ latex esrelation.ins
+
++ run latex (or pdflatex) on esrelation.dtx to generate documentation (including detailed installation instructions)
+ > $ pdflatex esrelation.dtx
+
++ determine the location of your local TeX tree by running
+ > $ kpsewhich --var-val TEXMFLOCAL
+
+ (this value will henceforth be referred to as ‘TEXMFLOCAL’)
+
++ install esrelation.sty and uesrelation.fd in
+ > TEXMFLOCAL/tex/latex/esrelation
+
++ install esrelation.mf and esrelation10.mf in
+ > TEXMFLOCAL/fonts/source/public/esrelation
+
++ install esrelation10.pfb in
+ > TEXMFLOCAL/fonts/type1/public/esrelation
+
++ install esrelation.map in
+ > TEXMFLOCAL/fonts/map/dvips/esrelation
+
+**NB**: all created directories should be set to mode 755 and all of the above files should be set to mode 644.
+
++ update LaTeX font database
+ > $ sudo -H mktexlsr
+
++ update TeX font map
+ > $ sudo -H updmap-sys --enable Map=esrelation.map
+
++ udpate the font database again
+ > $ sudo -H mktexlsr
+
+Resources
+---------
+
+Up-to-date source code is hosted on [GitHub](https://github.com/reinfurt/ESRELATION).

+%The program termination problem, also known at the uniform halting problem, can be defined as: \emph{Using a finite amount of time: determine whether a given program will always finish running or could possibly execute forever.}\\
+%
+%The Metafont programming and \LaTeXe{} package writing and \TeX macro programming (\emph{especially the \TeX macro programming}) required to produce these symbols looked like it might, itself, never end. It took more than a year of work in fits and starts to understand how the jalopy of bits and pieces go together to make a font work with \LaTeX{}. The Comprehensive \LaTeXe{} Symbol List (http://www.ctan.org/tex-archive/info/symbols/comprehensive/) does not currently include this set, but on completion all of these files will be ready to upload in the correct formats for inclusion. These are implemented as a standard \TeX{} math symbol font, implemented with custom Metafont sources, rendered on-the-fly as needed by \LaTeXe{}. Also provided in this package is a PostScript Type~1 version of the font. Symbols are accessed through macros defined in this package.\\
+%
+%Installation involves copying the supplied files to their designated places within \LaTeX{}'s search path and updating \TeX{}'s databases.
+%
+%\begin{enumerate}
+%\item
+%First, you need to find the folder \texttt{texmf-local} (on Unix the default is \texttt{/usr/local/texlive/texmf-local}). To do that, run:
+%
+%\texttt{kpsewhich --var-value TEXMFLOCAL}
+%
+%Subsequently, this directory will be referred to as \texttt{TEXMFLOCAL}.
+%
+%\item
+%Run \LaTeX{} on \texttt{esrelation.ins}.
+%Copy the files into the following directories, creating subdirectories as necessary:
+%
+%\begin{itemize}
+%\item copy \texttt{esrelation.sty} and \texttt{uesrelation.fd} to:\\
+%\texttt{TEXMFLOCAL/tex/latex/esrelation}
+%
+%\item copy \texttt{esrelation.mf} and \texttt{esrelation10.mf} to:\\
+%\texttt{TEXMFLOCAL/fonts/source/public/esrelation}
+%\end{itemize}
+%
+%If you also want to install the fonts in Type1 format:
+%\begin{itemize}
+%\item copy \texttt{esrelation10.pfb} to:\\
+%\texttt{TEXMFLOCAL/fonts/type1/public/esrelation}
+%
+%\item copy \texttt{esrelation.map} to:\\
+%\texttt{TEXMFLOCAL/fonts/map/dvips/esrelation}
+%
+%\end{itemize}
+%
+%Note that all created directories should be set to mode \texttt{755} and all files should be set to mode \texttt{644}.
+%
+%
+%\item
+%Update your \LaTeX{} font database. This is called the ls-r and lives in a few places. Fortunately, you can just run this, likely as sudo or root (\texttt{-H} sets \texttt{HOME} for the sudo environment):
+%
+%\texttt{sudo -H mktexlsr}
+%
+%\item
+%Update your \TeX{} font map by running the command:
+%
+%\texttt{sudo -H updmap-sys --enable Map=esrelation.map}
+%
+%\item
+%Update the font database again:
+%
+%\texttt{sudo -H mktexlsr}
+%
+%\item
+%Open \LaTeX{}, and start relating.
+%\end{enumerate}
