-DESCRIPTION
------------
-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.
-
-Note that 'git init' is the same as 'git init-db'. The command
-was primarily meant to initialize the object database, but over
-time it has become responsible for setting up the other aspects
-of the repository, such as installing the default hooks and
-setting the configuration variables. The old name is retained
-for backward compatibility reasons.
