 % Two LaTeX runs are required to ensure this document is up-to-date

 % It can take a long time to sort the index, so use the optimize
 % option. This has values: off (no optimize, sorting is done every
 % run), low (sort every second run) or high (write sorted database
 % to file and read in next time round). Don't modify the
 % index/glossary databases while the optimize option is set to
 % high. Do the modifications while the optimize option is set to
 % low or off. Alternatively, delete the .aux and .gidx files before rerunning
 % LaTeX.

 % Define some convenient commands

\newcommand*{\principleloc}[1]{\textbf{#1}}
\newcommand*{\appname}[1]{\texttt{#1}}

 % Later we'll switch to a fancy small caps Roman page numbering

\newcommand*{\myscroman}[1]{%
  \myscromannum{\value{#1}}%
}

\newcommand*{\myscromannum}[1]{%
  \textsc{\romannumeral#1}%
}

 % Now we need to add this as a possible location type

\DTLgidxAddLocationType{myscromannum}

 % Don't let \appname interfere with the sorting and labelling of
 % terms:

\appto\newtermlabelhook{\let\appname\DTLgidxNoFormat}

 % (datagidx also does this for \MakeUppercase, \MakeTextUppercase,
 % \MakeLowercase, \MakeTextLowercase, \textsc and \acronymfont.)

 % Make an index database labelled 'index' with given title.

\newgidx{index}{Index}

 % Define some terms for the index (entries must be defined in the
 % preamble).

 % Either use "database" key in optional argument
 % or set the default database. It's less typing to set the default
 % database, so let's do that:

\DTLgidxSetDefaultDB{index}

 % All the following definitions will add terms to the "index" database:

 % accent commands get stripped from the default label and sort
 % so the following gets both the label and sort set to 'macedoine'
\newterm{mac\'edoine}

 % The following gets both the label and sort set to 'macrame'
 % (This is only tested with utf8. It most likely won't work with
 % other encodings.)
\newterm{macramé}

 % Take care if the first letter starts with an accent.
 % The initial accented letter must be grouped to ensure it works
 % with \makefirstuc, but this will make the default label '{e}lite'
 % rather than 'elite', so let's override the default:

\newterm[label=elite]{{é}lite}

 % Sometimes the default sort may not suit your requirements. In
 % which case you can override it:

\title{Sample Document Using the datagidx Package}
\author{Nicola L. C. Talbot}

\begin{document}
\pagenumbering{roman}

The datagidx package was developed to follow the word order indexing
style described by the Oxford Style Manual. Many of the examples
here are taken from that manual. Two \LaTeX\ runs are required. If
you get a pdfTeX warning that a destination has been referenced but
does not exist, this may mean the index is out-of-date and you need
to do another \LaTeX\ run.

With word ordering a word break (space or hyphen) comes before all
other letters of the alphabet (\gls{sea lion} comes before \gls{seal}). 
With letter ordering word breaks are ignored (so \gls{seal} comes
before \gls{sea lion}).

Use a few terms here: \gls{index}, \gls{group}, \gls{singular}, \gls{plural}.

We don't need to use \gls{makeindex} or \gls{xindy}!
However, \TeX\ takes longer to sort and collate than either
\gls{makeindex} or \gls{xindy}, so document compilation time will
take longer.
