hg-ssh: read-only flag Allows you to restrict a ssh key to have read-only access to a set of repos by passing the --read-only flag to hg-ssh. This is useful in an environment where the number of unix users you can or are willing to create is limited. In such an environment, multiple users or applications will share a single unix account. Some of those applications will likely need read-only access to the repository. This change makes it possible to grant them such access without requiring that they use a separate unix account.
