It verifies that the directory has the magic file

By default, only the `upload-pack` service is enabled, which serves

The GIT_HTTP_EXPORT_ALL environmental variable may be passed to
'git-http-backend' to bypass the check for the "git-daemon-export-ok"
file in each repository before allowing export of that repository.

The backend process sets GIT_COMMITTER_NAME to '$REMOTE_USER' and
GIT_COMMITTER_EMAIL to '$\{REMOTE_USER}@http.$\{REMOTE_ADDR\}',
ensuring that any reflogs created by 'git-receive-pack' contain some
