+ Git.
+======
+
+Setup git.
+==========
+
+Debian.
+-------
+
+For Etch Degian release use git-core package from backports,
+old 1.4 version of git very dumb compared to new version 1.5::
+
+  $ sudo apt-get install git-core
+
+After install setup some options::
+
+  $ git config --global user.name "Oleksandr Gavenko"
+  $ git config --global user.mail "gavenkoa@gmail.com"
+  $ cat ~/.gitconfig
+  [user]
+    name = Oleksandr Gavenko
+    mail = gavenkoa@gmail.com
+
+Windows.
+--------
+
+No official support for Windows OS.
+
+Cygwin.
+-------
+
+  $ setup.exe -p git
+
+git over proxy.
+===============
+
+Only http:// protocol support proxy (not git://)::
+
+  $ export http_proxy="http://username:password@proxy:port/"
+  $ git clone http://github.com/$user/$proj.git $proj
+
+You can store proxy settings under repository local config file::
+
+  $ git config http.proxy http://$user:$passwd@$ip:$port
+
+Start your project.
+===================
+
+Setup proj space on fs::
+
+  $ mkdir proj
+  $ cd proj
+  $ git init
+  Initialized empty Git repository in /home/user/tmp/proj/.git/
+  $ ls -a
+  . .. .git
+
+Add file, make changes, commit all::
+
+  $ emacs Makefile
+  ... C-x C-c
+  $ emacs app.c
+  ... C-x C-c
+  $ git add Makefile app.c
+  $ git status
+  # On branch master
+  #
+  # Initial commit
+  #
+  # Changes to be committed:
+  #   (use "git rm --cached <file>..." to unstage)
+  #
+  #       new file: Makefile
+  #       new file: app.c
+  #
+
+or just::
+
+  $ git add .
+
+Commit newlly added file::
+
+  $ git commit
+  ... Write message log ...
+  Created initial commit 2169263: My first commit massage.
+   1 files changed, 4 insertions(+), 0 deletions(-)
+   create mode 100644 app.c
+
+Undo tracking added file.
+=========================
+
+You do::
+
+  $ git add badfile
+  $ git status
+  # On branch master
+  # Changes to be committed:
+  #   (use "git reset HEAD <file>..." to unstage)
+  #
+  #       new file:   badfile
+  #
+
+To stop tracking badfile do::
+
+  $ git rm --cached badfile
+  $ git status
+  # On branch master
+  # Untracked files:
+  #   (use "git add <file>..." to include in what will be committed)
+  #
+  #       file
+  nothing added to commit but untracked files present (use "git add" to track)
+
+or::
+
+  $ git reset badfile
+
+Doing changes.

+============================
+
+git does not directly support such feature. You can emulate it by::
+
+  $ git fetch
+  $ git log master..origin/master   # or just '..origin/master'

+By previous commands you grab changes from remote server! You can apply them::
