+XSL INCLUDES

+References to XSL paths should use the public URLs, such as:
+  http://docbook.sourceforge.net/release/xsl/current/xhtml/docbook.xsl
+If this fails to work for you, then there is a problem with your system
+catalogs.  As a work-around, you can adjust the OS-Fixups script and then:
+$ make os-fixup
+
+As an example of how this should normally work, on a FreeBSD system the
+resolution goes to /usr/local/share/xml/catalog which contains a directive:
+  <nextCatalog catalog="/usr/local/share/xml/catalog.ports" />
+to pull in the file automatically maintained by the Ports system.  That file
+will contain:
+  <delegateSystem
+   systemIdStartString="http://docbook.sourceforge.net/release/xsl/"
+   catalog="file:///usr/local/share/xsl/docbook/catalog" />
+  <delegateURI
+   uriStartString="http://docbook.sourceforge.net/release/xsl/"
+   catalog="file:///usr/local/share/xsl/docbook/catalog" />
+and that catalog file contains:
+  <rewriteSystem
+   systemIdStartString="http://docbook.sourceforge.net/release/xsl/current"
+   rewritePrefix="file:///usr/local/share/xsl/docbook" />
+  <rewriteURI
+   uriStartString="http://docbook.sourceforge.net/release/xsl/current"
+    rewritePrefix="file:///usr/local/share/xsl/docbook" />

-August 2007: A further feature has been added to Tidytxt. The current version
-of xmlto makes HTML that contains non-ASCII Unicode characters. Fortunately,
-they are few. The heading uses "box drawing" characters in the range U+2500 to
-U+253F, and within the main text, U+00A0 (hard space) occasionally appears. The
-Tidytxt script now turns all the former into hyphens and the latter into normal
-spaces. Bullets, which are set as U+25CF, are turned into asterisks. (It might
-be possible to do all this in the same way as I dealt with copyright - see
