\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}{pr-sources}
\bibinput{bibsample}

\usepackage[xindy]{imakeidx}
\makeindex[name=pr-sources, 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}{pr-sources}| makes an exception for
  authors whose |entrysubtype| field matches the string |ancient| and
  instructs \textsf{icite} to have them indexed in an index named
  |pr-sources|.
\item To actually produce the index, |\printindex[pr-sources]| is
  needed at the end of the document.
\end{enumerate}
