DESCRIPTION
-----------
Shows the commit logs.

+The command takes options applicable to the `git rev-list`

OPTIONS
-------
--<n>::
- Limits the number of commits to show.
- Note that this is a commit limiting option, see below.
-
-<since>..<until>::
- Show only commits between the named two commits. When
- either <since> or <until> is omitted, it defaults to
- `HEAD`, i.e. the tip of the current branch.
- For a more complete list of ways to spell <since>
- and <until>, see linkgit:gitrevisions[7].
