# - Find DocBook/XML tools
# This module can be used to translate Docbook/XML files to different
# output formats using XSLT files. Currently support XSLT processors
# that can be used for DocBook:
# xsltproc
# saxon-6.5.x
# xalan-2.x
#
# Typical usage is:
# find_package(DocBook REQUIRED)
# include(${DocBook_USE_FILE})
# docbook_generate(manpage my-app.xml MANPAGE_FILE_LIST)
# foreach(file ${MANPAGE_FILE_LIST})
# ...
# endforeach(file)
#
# This modules uses the following variables that must be set before
# includign the USE_FILE:
# DOCBOOK_XSLT_PROCESSOR - select the xslt processor to use
#
# The following functions are provided:
# DOCBOOK_GENERATE(format inputFile output)
# This function determines the output file names from the input
# file, depending on the format and stores it as cmake list in
# output. The currently support formats for "manpage" and "html".
#
# The following variables are set by this module:
# DocBook_FOUND - True is DocBook processing is available
# DocBook_USE_FILE - Name of the USE_FILE
# DOCBOOK_XSLT_PROCESSOR - If not set, one of the available XSLT processors
#
