+2007-09-27  Andy Buckley  <andy@insectnation.org>
+
+	* Ready for the momentous 1.1.1 release.
+
+	* Removed "full screen" param from documentation PDF
+	configuration, since this is actually very annoying.
+
+	* Added Makefile to build distribution tarball.
+
+	* Fixed definition of \GeVovercsq, which was missing the second
+	power of c. Thanks to Jeroen Hegeman for the bug report.
+
+2005-12-12  Andy Buckley  <andy@insectnation.org>
+
+	* Added noprefixcmds option due to residual guilt about
+	contaminating everyone's command namespace.
+
+	* Made basic manual.
+
+	* Removed "derived" from default SIunits options.
+
+	* Added SIunits options passing.

+\abstract{%
+  The \hepunits package extends the existing (and excellent) \texpkg{SIunits}
+  package to support units commonly used in high-energy physics. HEP uses a
+  rather specialised set of units to describe measurements of energies, masses,
+  momenta, reaction cross-sections, luminosities and so-on. Using this package
+  will provide particle physicists with a consistent and accurate way to refer
+  to dimensionful HEP quantities.
+%
+}
+
+\section{Recommended usage}
+The basic usage mode for \hepunits is to place
+%
+\begin{snippet}
+\usepackage{hepunits}
+\end{snippet}
+%
+in the preamble of your document. \hepunits also supports the \texpkg{SIunits}
+optional arguments (\texopt{thickspace}, \texopt{amssymb} and so-on), which are
+passed on directly to the \texpkg{SIunits} package. By default the
+\texopt{mediumspace}, \texopt{thickqspace}, \texopt{squaren} and
+\texopt{textstyle} options are passed, but these can be overridden.
+\texopt{amssymb} and \texopt{squaren} are considered to be mutually exclusive
+options, but you can choose to pass neither option to \texpkg{SIunits} by using
+the \hepunits \texopt{noamssquareissue} option. Additionally, the \hepunits
+\texopt{notextstyle} option can be used to turn the \texpkg{SIunits}
+\texopt{textstyle} off. On the whole, though, you should be able to use
+\hepunits with no options in most circumstances and are likely only to need them
+if you want access to the binary or derived units (using \texopt{binary} and
+\texopt{derived}/\texopt{derivedinbase} respectively).
+
+Finally, the only \hepunits-specific option is \texopt{noprefixcmds}. This is
+discussed at the end of the document and is probably only useful for macro
+language pedants!\footnote{No offence intended to macro language pedants, of course\dots}
+
+
+\section{Requirements}
+\hepunits requires the \texpkg{SIunits}, \texpkg{xspace} and \texpkg{amsmath}
+packages to be installed as part of your \TeX{} distribution. I don't know of
+any distributions for which this isn't the case, so chances are you're safe to
+just install \hepunits and use it right away!
+
+
+\section{Provided units}
+The HEP units provided by \hepunits are listed in Tables \ref{tab:normunits} and
+\ref{tab:hepunits} below. All the example outputs have been produced with a
+command like |\unit{1.0}{|\texgen{unit}|}| where \texgen{unit} is one of the
+unit commands listed in the tables.

+\end{table}
+
+Note that a lot of these units have, for convenience, been provided as explicit
+commands with various SI prefixes, rather than just defining the base unit and
+using the \texpkg{SIunits} prescription for the prefixes. Let's give a demo in
+case you don't know what I'm waffling about\dots the ``usual'' \texpkg{SUunits}
+way of doing things is like this:
+|\unit{1.0}{\mega\eVoverc}|. This produces ``\unit{1.0}{\mega\eVoverc}''
+just like |\unit{1.0}{\MeVoverc}| would do.
+
+I've chosen to provide the explicit prefixed commands for convenience: choose
+your own favourite way (the same applies even more so for most of the non-HEP
+units). If you are bothered about the explictly prefixed commands clogging up
+the \LaTeX{} macro namespace then pass the \texopt{noprefixcmds} option to
+\hepunits and the offending commands won't be defined at all. This will make
+life awkward when it comes to inverse cross-sections as used for integrated
+luminosities, but with suitable use of \texcmd{invbarn} I'm sure you can make
+do.
+
+\section{Summary}
+\hepunits is a handy package for particle physicists who'd like their units to
+look right, with upright \micro{s} and properly italicised $c$s in the
+appropriate places. Fortunately most of the work has already been done by the
+marvellous \texpkg{SIunits} package and I've just provided a few more commands
+and an option passing wrapper on to that excellent piece of work.
+
+If you have any comments, criticism, huge cash donations etc., then please do
+send them my way. Email to |andy@insectnation.org| is preferred, but if you can
+find a way to get your message to me by carrier pigeon I'll be very impressed.
