# docbook_convertToXhtmlChunk.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.---.
