# Convert an ODT into a PDF using "native" or "jodconverter" or "pyodconverter" or "unoconv" tool.
# Dolibarr variable MAIN_ODT_AS_PDF must be defined ...
#  to value "libreoffice" to call soffice native exporter feature (in such a case, this script is useless)
#  or value "unoconv" to call unoconv CLI tool after ODT generation.
#  or value "pyodconverter" to call DocumentConverter.py after ODT generation.
#  or value "jodconverter" to call jodconverter wrapper after ODT generation
#  or value "/pathto/jodconverter-cli-file.jar" to call jodconverter java tool without wrapper after ODT generation.
# Dolibarr variable MAIN_DOL_SCRIPTS_ROOT must be defined to path of script directories (otherwise dolibarr will try to guess).
#
# NOTE: Using this script is deprecated, you can now convert generated ODT to PDF on the fly by setting the value MAIN_ODT_AS_PDF
# to 'libreoffice'. It requires only soffice (OpenOffice or LibreOffice) installed on server (use apt install soffice libreoffice-common libreoffice-writer).
# If you got this error: javaldx failed! Warning: failed to read path from javaldx with no return to prompt when running soffice --headless -env:UserInstallation=file:"/tmp" --convert-to pdf --outdir xxx ./yyy.odt,
# check that directory defined into env:UserInstallation parameters exists and is writeable.
