# Enabling and disabling pdsh options
#  defaults:
#  enabled:  readline, rsh, ssh, dshgroup, netgroups, exec
#  disabled: rms, mrsh, qshell, mqshell, xcpu, genders, nodeattr, machines,
#            nodeupdown

#  To build the various module subpackages, pass --with <pkg> on
#   the rpmbuild command line (if your rpm is a recent enough version)
#
#  Similarly, to disable various pdsh options pass --without <pkg> on
#   the rpmbuild command line.
#
#  This specfile also supports passing the --with and --without through
#   the environment variables PDSH_WITH_OPTIONS and PDSH_WITHOUT_OPTIONS.
#   e.g. PDSH_WITH_OPTIONS="qshell genders" rpmbuild ....
