 hail is a Ganeti IAllocator plugin that implements the instance

+placement and movement using the same algorithm as **hbal**\(1).
 
 The program takes input via a JSON-file containing current cluster
 state and the request details, and output (on stdout) a JSON-formatted
 response. In case of critical failures, the error message is printed
 on stderr and the exit code is changed to show failure.
 
+If the input file name is ``-`` (a single minus sign), then the request
+data will be read from *stdin*.
