+Policy-driven snapshot management and replication tools. Using ZFS for
+underlying next-gen storage. Primarily intended for Linux, but BSD use
+is supported and reasonably frequently tested.
+
+You can use sanoid to create, automatically thin, and monitor
+snapshots and pool health from a single eminently human-readable TOML
+config file at /etc/sanoid/sanoid.conf.
+
+DEPENDENCIES
+
+SANOID depends on the Perl module Config::IniFiles and will not
+operate without it. Config::IniFiles may be installed from CPAN,
+though the project strongly recommends using your distribution's
+repositories instead.
+
+SYNCOID depends on ssh, pv, gzip, lzop, and mbuffer. It can run with
+reduced functionality in the absence of any or all of the above. SSH
+is only required for remote synchronization.
+
+CRON
+
+If you use cron there is the need to ensure that only one instance of
+sanoid is run at any time (or else there will be funny error messages
+about missing snapshots, ...). It's also good practice to separate
+the snapshot taking and pruning so the later won't block the former
+in case of long running pruning operations. Following is the
+recommend setup for a standard install:
+
+*/15 * * * * root flock -n /var/run/sanoid/cron-take.lock -c \
+  "TZ=UTC sanoid --take-snapshots"
+*/15 * * * * root flock -n /var/run/sanoid/cron-prune.lock -c \
+  "sanoid --prune-snapshots"
+
+Adapt the timer interval to the lowest configured snapshot interval.
+
+CONFIGURATION
+
+SANOID won't do anything useful unless you tell it how to handle your
+ZFS datasets in `/etc/sanoid/sanoid.conf`.
+
+Take a look at the files `sanoid.defaults.conf` and `sanoid.conf` for
+all possible configuration options.
+
+Also have a look at the README.md for a simpler suggestion for
+`sanoid.conf`.
+
+SYNCOID is a command line utility that doesn't require any
+configuration, with all of its switches set at runtime.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
