Everyday GIT With 20 Commands Or So
===================================
-<<Basic Repository>> commands are needed by people who have a
-repository --- that is everybody, because every working tree of
-git is a repository.
-
-In addition, <<Individual Developer (Standalone)>> commands are
-essential for anybody who makes a commit, even for somebody who
-works alone.

If you work with other people, you will need commands listed in
the <<Individual Developer (Participant)>> section as well.
of git repositories.
-Basic Repository[[Basic Repository]]
-------------------------------------
-
-Everybody uses these commands to maintain git repositories.
-
- * gitlink:git-init[1] or gitlink:git-clone[1] to create a
- new repository.
-
- * gitlink:git-fsck[1] to check the repository for errors.
-
- * gitlink:git-prune[1] to remove unused objects in the repository.
-
- * gitlink:git-repack[1] to pack loose objects for efficiency.
-
- * gitlink:git-gc[1] to do common housekeeping tasks such as
- repack and prune.
-
-Examples
-~~~~~~~~
-
-Check health and remove cruft.::
-+
-------------
-$ git fsck <1>
-$ git count-objects <2>
-$ git repack <3>
-$ git gc <4>
-------------
-+
-<1> running without `\--full` is usually cheap and assures the
-repository health reasonably well.
-<2> check how many loose objects there are and how much
-disk space is wasted by not repacking.
-<3> without `-a` repacks incrementally. repacking every 4-5MB
-of loose objects accumulation may be a good rule of thumb.
-<4> it is easier to use `git gc` than individual housekeeping commands
-such as `prune` and `repack`. This runs `repack -a -d`.
-
-Repack a small project into single pack.::
-+
-------------
-$ git repack -a -d <1>
-$ git prune
-------------
-+
-<1> pack all the objects reachable from the refs into one pack,
-then remove the other packs.
