+   the git group may be not the primary group of all users).

 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.
 
-A shared repository allows users belonging to the same group to push into that
-repository. When specifying `--shared` the config variable "core.sharedRepository" 
-is set to 'true' so that directories under `$GIT_DIR` are made group writable
-(and g+sx, since the git group may be not the primary group of all users).
-
 Running `git-init-db` in an existing repository is safe. It will not overwrite
 things that are already there. The primary reason for rerunning `git-init-db`
 is to pick up newly added templates.
