This is sometimes needed to work with old scripts that
expect HEAD to be a symbolic link.
+core.logAllRefUpdates::
+ If true, `git-update-ref` will append a line to
+ "$GIT_DIR/logs/<ref>" listing the new SHA1 and the date/time
+ of the update. If the file does not exist it will be
+ created automatically. This information can be used to
+ determine what commit was the tip of a branch "2 days ago".
+ This value is false by default (no logging).

core.repositoryFormatVersion::
Internal variable identifying the repository format and layout
version.

+specify more than one branch for deletion. If the branch currently
+has a ref log then the ref log will also be deleted.
OPTIONS
-D::
Delete a branch irrespective of its index status.
+-l::
+ Create the branch's ref log. This activates recording of
+ all changes to made the branch ref, enabling use of date
+ based sha1 expressions such as "<branchname>@{yesterday}".
+
-f::
Force the creation of a new branch even if it means deleting
a branch that already exists with the same name.

DESCRIPTION

+ `<prefix>` itself, and have nothing in `<prefix>/`
+ directory. Note that the `<prefix>/` value must end

+ pair (e.g. '\{yesterday\}', '\{1 month 2 weeks 3 days 1 hour 1
+ second ago\}' or '\{1979-02-26 18:30:00\}') to specify the value
+ of the ref at a prior point in time. This suffix may only be
+ used immediately following a ref name and the ref must have an
+ existing log ($GIT_DIR/logs/<ref>).
+
* A suffix '{caret}' to a revision parameter means the first parent of
that commit object. '{caret}<n>' means the <n>th parent (i.e.

SYNOPSIS

DESCRIPTION
-----------
ref symlink to some other tree, if you have copied a whole
archive by creating a symlink tree).
+Logging Updates
+---------------
+If config parameter "core.logAllRefUpdates" is true or the file
+"$GIT_DIR/logs/<ref>" exists then `git-update-ref` will append
+a line to the log file "$GIT_DIR/logs/<ref>" (dereferencing all
+symbolic refs before creating the log name) describing the change
+in ref value. Log lines are formatted as:
+
+ . oldsha1 SP newsha1 SP committer LF
++
+Where "oldsha1" is the 40 character hexadecimal value previously
+stored in <ref>, "newsha1" is the 40 character hexadecimal value of
+<newvalue> and "committer" is the committer's name, email address
+and date in the standard GIT committer ident format.
+
+Optionally with -m:
+
+ . oldsha1 SP newsha1 SP committer TAB message LF
++
+Where all fields are as described above and "message" is the
+value supplied to the -m option.
+
+An update will fail (without changing <ref>) if the current user is
+unable to create a new log file, append to the existing log file
+or does not have committer information available.
