  Reflog is a mechanism to record when the tip of branches are

  The subcommand "show" (which is also the default, in the absence of any
  subcommands) will take all the normal log options, and show the log of
- `HEAD`, which will cover all recent actions, including branch switches.
- It is basically an alias for 'git log -g --abbrev-commit
- --pretty=oneline', see gitlink:git-log[1].

+ as well).  It is an alias for 'git log -g --abbrev-commit --pretty=oneline';
+ see linkgit:git-log[1].
+ 
+ The reflog is useful in various git commands, to specify the old value
+ of a reference. For example, `HEAD@\{2\}` means "where HEAD used to be
+ two moves ago", `master@\{one.week.ago\}` means "where master used to
+ point to one week ago", and so on. See linkgit:git-rev-parse[1] for
+ more details.
  
 +To delete single entries from the reflog, use the subcommand "delete"
 +and specify the _exact_ entry (e.g. ``git reflog delete master@\{2\}'').
