3 | # This is included in commands that either have to be run from the toplevel |
4 | # of the repository, or with GIT_DIR environment variable properly. | |
5 | # If the GIT_DIR does not look like the right correct git-repository, | |
6 | # it dies. | |

8 | # Having this variable in your environment would break scripts because |
9 | # you would cause "cd" to be be taken to unexpected places. If you | |
10 | # like CDPATH, define it for your interactive shell sessions without | |
11 | # exporting it. | |
