+-b::
+	Show blank SHA-1 for boundary commits.  This can also
+	be controlled via the `blame.blankboundary` config option.
+
+--root::
+	Do not treat root commits as boundaries.  This can also be
+	controlled via the `blame.showroot` config option.
+
+--show-stats::
+	Include additional statistics at the end of blame output.
+
+-L <start>,<end>::
+	Annotate only the given line range.  <start> and <end> can take
+	one of these forms:
+
+	- number
++
+If <start> or <end> is a number, it specifies an
+absolute line number (lines count from 1).
++
+
+- /regex/
++
+This form will use the first line matching the given
+POSIX regex.  If <end> is a regex, it will search
+starting at the line given by <start>.
++
+
+- +offset or -offset
++
+This is only valid for <end> and will specify a number
+of lines before or after the line given by <start>.
++
+
+-l::
+	Show long rev (Default: off).
+
+-t::
+	Show raw timestamp (Default: off).
+
+-S <revs-file>::
+	Use revisions from revs-file instead of calling linkgit:git-rev-list[1].
+
+--reverse::
+	Walk history forward instead of backward. Instead of showing
+	the revision in which a line appeared, this shows the last
+	revision in which a line has existed. This requires a range of
+	revision like START..END where the path to blame exists in
+	START.
+
+-p::
+--porcelain::
+	Show in a format designed for machine consumption.
+
+--incremental::
+	Show the result incrementally in a format designed for
+	machine consumption.
+
+--encoding=<encoding>::
+	Specifies the encoding used to output author names
+	and commit summaries. Setting it to `none` makes blame
+	output unconverted data. For more information see the
+	discussion about encoding in the linkgit:git-log[1]
+	manual page.
+
+--contents <file>::
+	When <rev> is not specified, the command annotates the
+	changes starting backwards from the working tree copy.
+	This flag makes the command pretend as if the working
+	tree copy has the contents of the named file (specify
+	`-` to make the command read from the standard input).
+
+--date <format>::
+	The value is one of the following alternatives:
+	{relative,local,default,iso,rfc,short}. If --date is not
+	provided, the value of the blame.date config variable is
+	used. If the blame.date config variable is also not set, the
+	iso format is used. For more information, See the discussion
+	of the --date option at linkgit:git-log[1].
+
+-M|<num>|::
+	Detect moving lines in the file as well.  When a commit
+	moves a block of lines in a file (e.g. the original file
+	has A and then B, and the commit changes it to B and
+	then A), the traditional 'blame' algorithm typically blames
+	the lines that were moved up (i.e. B) to the parent and
+	assigns blame to the lines that were moved down (i.e. A)
+	to the child commit.  With this option, both groups of lines
+	are blamed on the parent.
++
+<num> is optional but it is the lower bound on the number of
+alphanumeric characters that git must detect as moving
+within a file for it to associate those lines with the parent
+commit.
+
+-C|<num>|::
+	In addition to `-M`, detect lines copied from other
+	files that were modified in the same commit.  This is
+	useful when you reorganize your program and move code
+	around across files.  When this option is given twice,
+	the command additionally looks for copies from all other
+	files in the parent for the commit that creates the file.
++
+<num> is optional but it is the lower bound on the number of
+alphanumeric characters that git must detect as moving
+between files for it to associate those lines with the parent
+commit.
+
+-h::
+--help::
+	Show help message.
