       git-init - Create an empty Git repository or reinitialize an existing one

       git init [-q | --quiet] [--bare] [--template=<template_directory>]
		 [--separate-git-dir <git dir>]
		 [--shared[=<permissions>]] [directory]

       This command creates an empty Git repository - basically a .git directory with
       subdirectories for objects, refs/heads, refs/tags, and template files. An initial HEAD
       file that references the HEAD of the master branch is also created.

       If the $GIT_DIR environment variable is set then it specifies a path to use instead of
       ./.git for the base of the repository.

       If the object storage directory is specified via the $GIT_OBJECT_DIRECTORY environment
       variable then the sha1 directories are created underneath - otherwise the default
       $GIT_DIR/objects directory is used.

       Running git init in an existing repository is safe. It will not overwrite things that are
       already there. The primary reason for rerunning git init is to pick up newly added
       templates (or to move the repository to another place if --separate-git-dir is given).

       -q, --quiet
	   Only print error and warning messages, all other output will be suppressed.

	   Create a bare repository. If GIT_DIR environment is not set, it is set to the current
	   working directory.

	   Specify the directory from which templates will be used. (See the "TEMPLATE DIRECTORY"
	   section below.)

       --separate-git-dir=<git dir>
	   Instead of initializing the repository where it is supposed to be, place a
	   filesytem-agnostic Git symbolic link there, pointing to the specified path, and
	   initialize a Git repository at the path. The result is Git repository can be separated
	   from working tree. If this is reinitialization, the repository will be moved to the
	   specified path.

	   Specify that the Git repository is to be shared amongst several users. This allows
	   users belonging to the same group to push into that repository. When specified, the
	   config variable "core.sharedRepository" is set so that files and directories under
	   $GIT_DIR are created with the requested permissions. When not specified, Git will use
	   permissions reported by umask(2).

       The option can have the following values, defaulting to group if no value is given:

       o   umask (or false): Use permissions reported by umask(2). The default, when --shared is
	   not specified.

       o   group (or true): Make the repository group-writable, (and g+sx, since the git group
	   may be not the primary group of all users). This is used to loosen the permissions of
	   an otherwise safe umask(2) value. Note that the umask still applies to the other
	   permission bits (e.g. if umask is 0022, using group will not remove read privileges
	   from other (non-group) users). See 0xxx for how to exactly specify the repository

       o   all (or world or everybody): Same as group, but make the repository readable by all

       o   0xxx: 0xxx is an octal number and each file will have mode 0xxx.  0xxx will override
	   users' umask(2) value (and not only loosen permissions as group and all does).  0640
	   will create a repository which is group-readable, but not group-writable or accessible
	   to others.  0660 will create a repo that is readable and writable to the current user
	   and group, but inaccessible to others.

       By default, the configuration flag receive.denyNonFastForwards is enabled in shared
       repositories, so that you cannot force a non fast-forwarding push into it.

       If you name a (possibly non-existent) directory at the end of the command line, the
       command is run inside the directory (possibly after creating it).

       The template directory contains files and directories that will be copied to the $GIT_DIR
       after it is created.

       The template directory used will (in order):

       o   The argument given with the --template option.

       o   The contents of the $GIT_TEMPLATE_DIR environment variable.

       o   The init.templatedir configuration variable.

       o   The default template directory: /usr/share/git-core/templates.

       The default template directory includes some directory structure, some suggested "exclude
       patterns", and copies of sample "hook" files. The suggested patterns and hook files are
       all modifiable and extensible.

       Start a new Git repository for an existing code base

	       $ cd /path/to/my/codebase
	       $ git init      (1)
	       $ git add .     (2)

	   1. prepare /path/to/my/codebase/.git directory
	   2. add all existing file to the index
