+bees (Best-Effort Extent-Same) is a block-oriented userspace
+deduplication agent designed for large btrfs filesystems. It is an
+offline dedupe combined with an incremental data scan capability to
+minimize time data spends on disk from write to dedupe.
+
+Strengths:
+  * Space-efficient hash table and matching algorithms - can use as
+    little as 1 GB hash table per 10 TB unique data (0.1GB/TB)
+  * Daemon incrementally dedupes new data using btrfs tree search
+  * Works with btrfs compression - dedupe any combination of compressed
+    and uncompressed files
+  * Works around btrfs filesystem structure to free more disk space
+  * Persistent hash table for rapid restart after shutdown
+  * Whole-filesystem dedupe - including snapshots
+  * Constant hash table size - no increased RAM usage if data set
+    becomes larger
+  * Works on live data - no scheduled downtime required
+  * Automatic self-throttling based on system load
+
+Weaknesses:
+  * Whole-filesystem dedupe - has no include/exclude filters, does not
+    accept file lists
+  * Requires root privilege (or CAP_SYS_ADMIN)
+  * First run may require temporary disk space for extent reorganization
+  * First run may increase metadata space usage if many snapshots exist
+  * Constant hash table size - no decreased RAM usage if data set
+    becomes smaller
+  * btrfs only
+
+After installing, edit /etc/rc.d/rc.bees.conf, /etc/logrotate.d/bees,
+and /etc/bees/*.conf, and ensure /etc/rc.d/rc.bees is started from
+/etc/rc.d/rc.local. To drastically reduce the amount of logging it is
+recommended to add "-v 6" to OPTIONS in /etc/bees/*.conf.

+# 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.
