# 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.
