git config file

http://www.kernel.org/pub/software/scm/git/docs/git-config.html

If not set explicitly with --file, there are three files where git config will search for configuration options:

$GIT_DIR/config

Repository specific configuration file. (The filename is of course relative to the repository root, not the working directory.)

~/.gitconfig

User-specific configuration file. Also called "global" configuration file.

$(prefix)/etc/gitconfig

System-wide configuration file.
