+arguments) on a Btrfs file system and measures used compression types and
+effective compression ratio, producing a report.
+
+A directory has no extents but has a (recursive) list of files. A non-regular
+file is silently ignored.
+
+As it makes no sense to talk about compression ratio of a partial extent,
+every referenced extent is counted whole, exactly once -- no matter if you use
+only a few bytes of a 1GB extent or reflink it a thousand times. Thus, the
+uncompressed size will not match the number given by @command{tar} or
+@command{du}. On the other hand, the space used should be accurate (although
+obviously it can be shared with files outside our set).")
