\textbf{\textsf{icite sample file}} --- \cczero\ This
file is public domain

\section*{Preamble}
This file demonstrates how \textsf{icite} can be used to produce an
index of passages cited without using either \hologo{BibTeX} or
Bib\LaTeX.

The relevant part of the preamble which is used here follows:
\begin{Verbatim}
\usepackage[defaultindex=none, nobibengine]{icite}
\IndexSubtypeAs{ancient}{icite-nobiblatex-primary}
\bibinput{bibsample}

\usepackage{classics}
\newclassic{plat}{#1|#1|#1}
\newclassic{arist}{#1|\textit{#1}|#1}

\usepackage[xindy]{imakeidx}
\makeindex[name=icite-nobiblatex-primary, title={Index locorum citatorum}]
\end{Verbatim}

\paragraph{Remarks}
\begin{enumerate}
\item |defaultindex=none| disables indexing by default.
\item |nobibengine| instructs \textsf{icite} to insert the citations
  in the body text without using either \hologo{BibTeX} or Bib\LaTeX.
\item |\IndexSubtypeAs{ancient}{icite-nobiblatex-primary}| makes an
  exception for authors whose |entrysubtype| field matches the string
  |ancient| and instructs \textsf{icite} to have them indexed in an
  index named\\ |icite-nobiblatex-primary|.
\item To actually produce the index,
  |\printindex[icite-nobiblatex-primary]| is needed at the end of the
  document.
\end{enumerate}
