+# Script to pre-process XML input before processing it for various purposes.
+# Options specify which transformations are to be done. Monospaced literal
+# layout blocks are never touched.
+
+# Changes:
+
+# -abstract: Remove the <abstract> element
+
+# -ascii:    Replace &8230;   (sic, no x) with ...
+#            Replace &#x2019; by '
+#            Replace &#x201C; by "
+#            Replace &#x201D; by "
+#            Replace &#x2013; by -
+#            Replace &#x2020; by *
+#            Replace &#x2021; by **
+#            Replace &#x00a0; by a space
+#            Replace &#169;   by (c)
+#            Put quotes round <literal> text
+#            Put quotes round <quote> text
+
+# -bookinfo: Remove the <bookinfo> element from the file
+
+# -fi:       Replace "fi" by &#xFB01; except when it is in an XML element, or
+#            inside a <literal>.
+
+# -noindex   Remove the XML to generate a Concept and an Options index.
+# -oneindex  Ditto, but add XML to generate a single index.
+
+
+
+# The function that processes non-literal monospaced text
+
+sub process()
