+-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>::
+-L :<funcname>::
+	Annotate only the given line range. May be specified multiple times.
+	Overlapping ranges are allowed.
++
+<start> and <end> are optional. ``-L <start>'' or ``-L <start>,'' spans from
+<start> to end of file. ``-L ,<end>'' spans from start of file to <end>.

+include::line-range-format.txt[]
+
+-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 <rev>..<rev>::
+	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.  `git blame --reverse START` is taken as `git blame
+	--reverse START..HEAD` for convenience.
+
+-p::
+--porcelain::
+	Show in a format designed for machine consumption.
+
+--line-porcelain::
+	Show the porcelain format, but output commit information for
+	each line, not just the first time a commit is referenced.
+	Implies --porcelain.
+
+--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>::
+	Specifies the format used to output dates. 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 supported values, see the discussion
+	of the --date option at linkgit:git-log[1].
+
+--[no-]progress::
+	Progress status is reported on the standard error stream
+	by default when it is attached to a terminal. This flag
+	enables progress reporting even if not attached to a
+	terminal. Can't use `--progress` together with `--porcelain`
+	or `--incremental`.
+
+-M[<num>]::
+	Detect moved or copied lines within a file. When a commit
+	moves or copies a block of lines (e.g. the original file
+	has A and then B, and the commit changes it to B and then
+	A), the traditional 'blame' algorithm notices only half of
+	the movement and 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 by
+	running extra passes of inspection.
++
+<num> is optional but it is the lower bound on the number of
+alphanumeric characters that Git must detect as moving/copying
+within a file for it to associate those lines with the parent
+commit. The default value is 20.
+
+-C[<num>]::
+	In addition to `-M`, detect lines moved or 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 other
+	files in the commit that creates the file. When this
+	option is given three times, the command additionally
+	looks for copies from other files in any commit.
++
+<num> is optional but it is the lower bound on the number of
+alphanumeric characters that Git must detect as moving/copying
+between files for it to associate those lines with the parent
+commit. And the default value is 40. If there are more than one
+`-C` options given, the <num> argument of the last `-C` will
+take effect.
+
+--ignore-rev <rev>::
+	Ignore changes made by the revision when assigning blame, as if the
+	change never happened.  Lines that were changed or added by an ignored
+	commit will be blamed on the previous commit that changed that line or
+	nearby lines.  This option may be specified multiple times to ignore
+	more than one revision.  If the `blame.markIgnoredLines` config option
+	is set, then lines that were changed by an ignored commit and attributed to
+	another commit will be marked with a `?` in the blame output.  If the
+	`blame.markUnblamableLines` config option is set, then those lines touched
+	by an ignored commit that we could not attribute to another revision are
+	marked with a '*'.
+
+--ignore-revs-file <file>::
+	Ignore revisions listed in `file`, which must be in the same format as an
+	`fsck.skipList`.  This option may be repeated, and these files will be
+	processed after any files specified with the `blame.ignoreRevsFile` config
+	option.  An empty file name, `""`, will clear the list of revs from
+	previously processed files.
+
+-h::
+	Show help message.
