# IMPORTANT
#
# 1. we first dry-run rsync with change summary to find out
# if there are any changes and code generation is needed.
# 2. normally, to get current state or target host, we run
# such operations in type explorers, but that's not
# possible due to how rsync works.
# 3. redirecting output of dry-run to stderr to ease debugging.
# 4. to understand how that cryptic regex works, please
# open rsync manpage and read about --itemize-changes.
