Multiwerf werf-path and exec commands will try to use trdl.
Only in the case when trdl has been downloaded and installed by the multiwerf update or multiwerf use commands.
This behavior confirms with werf-path and exec commands behaviour, which will complain if werf has not been installed yet.
--try-trdl='yes|no' flag enables or disables usage of trdl.
--auto-download-trdl='yes|no|on-self-update(default)' flag controls whether multiwerf will try to install trdl if it is not installed in the system yet.
By default multiwerf will auto install trdl unless --self-update=no flag is set.
User can force auto install of trdl in that case by an explicit --auto-download-trdl=yes option.
