+# Possible pipelines:
+#
+# dblatex:
+# This converts the docbook content to latex and leave it to latex
+# to format it. Index ranges are broken in oldstable, fixed in jessie.
+#
+# xmlto:
+# Alternative processing path to dblatex is to use xmlto using fop
+# to create PDF like this. The PDF output (visual design) is
+# better, but the footnote handling is worse and images are missing.
+#
+# docbook-xsl:
+# Third alternative is to use xsltproc and fop directly, as
+# recommended by <URL: http://www.sagehill.net/docbookxsl/index.html >.
+# This include images, but the index refs and footnote/endnote handling
+# is broken.
