DESCRIPTION
-----------
You may find these things in your Git repository (`.git`
directory for a repository associated with your working tree, or
`<project>.git` directory for a public 'bare' repository. It is
also possible to have a working tree where `.git` is a plain
ASCII file containing `gitdir: <path>`, i.e. the path to the
real Git repository).
A Git repository comes in two different flavours:
* a `.git` directory at the root of the working tree;
* a `<project>.git` directory that is a 'bare' repository
(i.e. without its own working tree), that is typically used for
exchanging histories with others by pushing into it and fetching
from it.
*Note*: Also you can have a plain text file `.git` at the root of
your working tree, containing `gitdir: <path>` to point at the real
directory that has the repository. This mechanism is often used for
a working tree of a submodule checkout, to allow you in the
containing superproject to `git checkout` a branch that does not
have the submodule. The `checkout` has to remove the entire
submodule working tree, without losing the submodule repository.
These things may exist in a Git repository.
