+
+    Daemon to watch the health of HPC and RR instances.
+
+    This deamon uses HpcHealthCheck objects in the Data Model to conduct
+    periodic tests of HPC and RR nodes. Two types of Health Checks are
+    supported:
+
+       kind="dns": checks the request routers to make sure that a DNS
+         name is resolveable and returns the right kind of records.
+
+         resource_name should be set to the domain name to lookup.
+
+         result_contains is option and can be used to hold "A", "CNAME", or
+            a particular address or hostname that should be contained in the
+            query's answer.
+
+       kind="http": checks the hpc nodes to make sure that a URL can be
+         retrieved from the node.
+
+         resource_name should be set to the HostName:Url to fetch. For
+         example, cdn-stream.htm.fiu.edu:/hft2441/intro.mp4
+
+     In addition to the above, HPC heartbeat probes are conducted, similar to
+     the ones that dnsredir conducts.
+
+     The results of health checks are stored in a tag attached to the Instance
+     the healthcheck was conducted against. If all healthchecks of a particular
+     variety were successful for a instance, then "success" will be stored in
+     the tag. Otherwise, the first healthcheck to fail will be stored in the
+     tag.
