Today I installed on my VPS. I noticed that I can write some helper scripts around it and here they are.
You can download them from https://sirjofri.de/files/guidedreplica.
You can install it like that:
# bind your client $home to /n/rclient
# bind your server $home to /n/rserver
hget https://sirjofri.de/files/guidedreplica/guidedreplica.rc | rc
# follow the prompts
This will also install two helper scripts to $home/bin/rc/replica/. Reproto copies one proto over the other. You can choose which one you want to keep. Reupdate is helpful if there are update-update errors. It should automatically solve them (untested, but should work).
Update: has issues. Often it does a bad job tracking changes, leaving removed files there and vice versa. I never encountered data loss, only inconsistencies in the copies.
Many people use which does not overwrite changed files. At some point I will build some scripts around it and use that instead of
