# - Try to find db2pdf, and define a custom command to turn docbook into pdf
#
# Once done, this will define:
# DB2PDF_FOUND - system has LyX
# DB2PDF_COMMAND - the command to run
#
# and the following function:
# docbook_to_pdf(<output-variable> <docbook files>)
#
# Useful configuration variables you might want to add to your cache:
# DB2PDF_ROOT_DIR - A directory prefix to search
