I have a project that requires rsync with zstd compression and I would
like to have the option in ports without having to manually modify my
rsync port Makefile if possible. The zstd option is disabled in the
rsync port right now. This diff would add a flavor for zstd. I'm not
sure everyone would want zstd enabled globally but a flavor might work
instead? Thoughts?
