# docbook_setConversionXhtmlChunks.sh -- This function uses DocBook XML as
# input and applies XSL stylesheets to produce a directory with many
# XHTML files as output.  The procedure was taken from the
# documentation of `docbook-style-xsl-1.69.1-5.1' package, which says:
# ---To publish HTML from your XML documents, you just need an XSLT
# engine.---.
