-====== git ======
-git is a distributed version control system originally written by Linus Torvalds.  The version control metadata is distributed, so every clone is a complete history of the source code.  Compare this with centralized systems like SVN or CVS where, if the central repository burns down, everything is lost!

-====== Installing git ======
-====== Migrating from SVN ======
-  * Reference: http://www.jonmaddox.com/2008/03/05/cleanly-migrate-your-subversion-repository-to-a-git-repository/
-===== Install git-svn =====
-<code># aptitude install git-svn</code>
-===== Create a temp git repo =====
-This is where we will initially copy the SVN repository.
-<code>$ mkdir beca_lims_portal_temp
-$ cd beca_lims_portal_temp</code>
-==== Initialize temp git repo ====
-<code>$ git svn init https://172.26.17.2/svn/beca_lims_portal/trunk/ --no-metadata</code>
-===== Map SVN users to git =====
-==== Create an authors file ====
-///home/aorth/svnauthors//:
-<file>mnorling = Martin Norling <m.norling@cgiar.org>
-aorth = Alan Orth <a.orth@cgiar.org>
-root = Alan Orth <a.orth@cgiar.org>
-akihara = Absolomon Kihara <a.kihara@cgiar.org></file>
-==== Tell git about your authors ====
-<code>$ git config svn.authorsfile ~/svnauthors</code>
-===== Populate the temp git repo =====
-<code>$ git svn fetch</code>
-===== Clone from the temp repo =====
-When doing a normal git clone it will take everything we want from the temporary repository, while leaving behind all the SVN cruft that was there to support the git-svn  stuff.
-<code>$ cd ..
-$ git clone beca_lims_portal_temp beca_lims_portal</code>
-===== See the commit history =====
-You should see all your authors mapped from the SVN repository:
-<code>$ cd beca_lims_portal
-$ git log</code>
-====== Tagging ======
-Git uses two main types of tags: lightweight and annotated. A lightweight tag is very much like a branch that doesn’t change — it’s just a pointer to a specific commit. Annotated tags, however, are stored as full objects in the Git database. They’re checksummed; contain the tagger name, e-mail, and date; have a tagging message; and can be signed and verified with GNU Privacy Guard (GPG). It’s generally recommended that you create annotated tags so you can have all this information; but if you want a temporary tag or for some reason don’t want to keep the other information, lightweight tags are available too.
-Without arguments, ''git tag'' creates a "lightweight" tag that is basically a branch that never moves. Normally, you want to at least pass the ''-a'' option to create an unsigned tag.
-See:

-  * http://www.gitready.com/beginner/2009/02/03/tagging.html
-===== Tagging the current version =====
-<code>git tag -a v0.2</code>
-===== Tagging a past version =====
-Specify a certain commit by giving the commit's checksum (or the abbreviated checksum):
-<code>git tag -a v0.1 8e11e65</code>
-===== Pushing tags to origin =====
-By default ''git push'' doesn't send tags to the remote origin; you have to tell it to do it manually.
-==== Certain tag ====
-<code>$ git push origin v0.1</code>
-==== All tags ====
-Push all tags which are not already on the remote origin:
-<code>$ git push origin --tags</code>
-====== Configuration ======
-===== ~/.gitconfig =====
-==== Set a default editor ====
-The editor is used when you have to enter a commit message.
-<file>[core]
-    editor = vim</file>
-==== Colorize git output ====
-<file>[color]
-    ui = auto
-[color "branch"]
-    current = yellow reverse
-    local = yellow
-    remote = green
-[color "diff"]
-    meta = yellow bold
-    frag = magenta bold
-    old = red bold
-    new = green bold
-[color "status"]
-    added = yellow
-    changed = green
-    untracked = cyan</file>
