=head1 NAME
Config::GitLike::Git - load Git configuration files
=head1 SYNOPSIS
use Config::GitLike::Git;
my $config = Config::GitLike::Git->new;
$config->load("/path/to/repo");
=head1 DESCRIPTION
This is a modification of L<Config::GitLike> to look at the same
locations that Git writes to. Unlike with L<Config::GitLike>, you do
not need to pass a confname to its constructor. This module also
enables the L<Config::GitLike> option to maintain git compatibility
when reading and writing variables.
L<Config::GitLike/load> should be passed path to the top level of a
git repository -- this defaults to the current directory. It will
append C<.git> as necessary. It supports both bare and non-bare
repositories.
=head1 METHODS
This module overrides these methods from C<Config::GitLike>:
=head2 dir_file
The per-directory configuration file is F<.git/config>. With an
optional directory argument, will return a fully-qualified path to the
configuration file, as git would edit with C<git config --local -C path>.
=head2 user_file
The per-user configuration file is F<~/.gitconfig>
=head2 global_file
The per-host configuration file is F</etc/gitconfig>
=head2 is_git_dir
Returns true if a file contains the necessary files (as git would reckon
it) for the path to be a git repository.
=head2 load_dirs
Loads the relevant .git/config file.
