@kindex C-x v g
For some back ends, you can display the file @dfn{annotated} with
per-line version information and using colors to enhance the visual
-appearance, with the command @kbd{M-x vc-annotate}.
-It creates a new buffer (the ``annotate buffer'') displaying the
-file's text, with each part colored to show how old it is. Text
-colored red is new, blue means old, and intermediate colors indicate
-intermediate ages. By default, the time scale is 360 days, so that
-everything more than one year old is shown in blue.

When you give a prefix argument to this command, it uses the
minibuffer to read two arguments: which version number to display and
-annotate (instead of the current file contents), and a stretch factor
-for the time scale. A stretch factor of 0.1 means that the color
-range from red to blue spans the past 36 days instead of 360 days. A
-stretch factor greater than 1 means the color range spans more than a
-year.
