Logs are actually written out through an abstract LogFormatter
32
interface, which allows for different preferred formats. Plugins can
35
Logs can be produced in either forward (oldest->newest) or reverse
36
(newest->oldest) order.
38
Logs can be filtered to show only revisions matching a particular
39
search string, or within a particular range of revisions. The range
40
can be given as date/times, which are reduced to revisions before
43
In verbose mode we show a summary of what changed in each particular
44
revision. Note that this is the delta for changes in that revision
45
relative to its mainline parent, not the delta relative to the last
46
logged revision. So for example if you ask for a verbose log of
47
changes touching hello.c you will get a list of those revisions also
48
listing other things that were changed in the same revision, but not
49
all the changes since the previous revision that touched hello.c.
31
* from last to first or (not anymore) from first to last;
32
the default is "reversed" because it shows the likely most
33
relevant and interesting information first
