I have set up a remote Mercurial (Hg) repository that holds a large Java project. I would like to monitor any changes done to the project's pom file and receive e-mails when changes were made to the pom.

I would like to exclude all other file changes from notifications as I am only interested in monitoring any possible changes in dependencies (hence the POM). Is there any Mercurial Extension or workaround using Jenkins to subscribe to the change history for one individual file inside a Mercurial repo?
