ruby-remctl 3.10-1ubuntu1 (s390x binary) in ubuntu xenial

 remctl is a client/server protocol for executing specific commands on a
 remote system with Kerberos authentication. The allowable commands must
 be listed in a server configuration file, and the executable run on the
 server may be mapped to any command name. Each command is also
 associated with an ACL containing a list of Kerberos principals
 authorized to run that command.
 .
 This package contains the Ruby remctl extension, which provides native
 Ruby bindings for the libremctl client library.
