  10--------
  11'git-init-db' [--template=<template_directory>] [--shared]
  12
  13
  14OPTIONS
  15-------
  16--template=<template_directory>::
  17        Provide the directory in from which templates will be used.
  18
  19--shared::
  20        Specify that the git repository is to be shared amongst several users.
  21

  23DESCRIPTION
  24-----------
  25This simply creates an empty git repository - basically a `.git` directory
  26and `.git/object/??/`, `.git/refs/heads` and `.git/refs/tags` directories,
  27and links `.git/HEAD` symbolically to `.git/refs/heads/master`.
  28
  29If the `$GIT_DIR` environment variable is set then it specifies a path
  30to use instead of `./.git` for the base of the repository.
  31
  32If the object storage directory is specified via the `$GIT_OBJECT_DIRECTORY`
  33environment variable then the sha1 directories are created underneath -
  34otherwise the default `$GIT_DIR/objects` directory is used.
  35
  36A shared repository allows users belonging to the same group to push into that
  37repository. When specifying `--shared` the config variable "core.sharedRepository" 
  38is set to 'true' so that directories under `$GIT_DIR` are made group writable
  39(and g+sx, since the git group may be not the primary group of all users).
  40
  41
  42Running `git-init-db` in an existing repository is safe. It will not overwrite
  43things that are already there. The primary reason for rerunning `git-init-db`
  44is to pick up newly added templates.
