|
|
This command creates a buffer that shows, for each line of the current
|
|
file, when it was last edited and by whom. Additionally, colors are
|
|
used to show the age of each line--blue means oldest, red means
|
|
youngest, and intermediate colors indicate intermediate ages. By
|
|
default, the time scale stretches back one year into the past;
|
|
everything that is older than that is shown in blue.
|
|
|
|
With a prefix argument, this command asks two questions in the
|
|
minibuffer. First, you may enter a revision number REV; then the buffer
|
|
displays and annotates that revision instead of the working revision
|
|
\(type RET in the minibuffer to leave that default unchanged). Then,
|
|
you are prompted for the time span in days which the color range
|
|
should cover. For example, a time span of 20 days means that changes
|
|
over the past 20 days are shown in red to blue, according to their
|
|
age, and everything that is older than that is shown in blue.
