+duperemove(rb)
+==============
+
+Replaces `duperemove`s dedupe-functionality.
+It is an own program, which uses the database like `duperemove`.
+While `duperemove` scans directories and builds database, this program only dedupes files extents.
+
+The advantage is, duperemoverb allowes incremental/partial deduplications.
+While duperemove deduplicates any files registered in database, you can give a path, which files to deduplicate.
+Files outside this path will be ignored, but will be deduplicated, if it shares same digests like extends of file inside this path.
+
+Partial deduplication
+---------------------
+
+* /a/1 has two extents: 0x12, 0x54
+* /b/1 has two extents: 0x54, 0xa8
+* /b/2 has two extents: 0x90, 0xa8
+
+If you call `duperemoverb dedupe /a`, `/b/1` and `/b/2` will be ignored, but the first extent of `/b/1` will be deduplicated with `/a/1` second extent.
