# We support three different client categories:
# 1) Clients with new style complete command where output is like:
#
# cmds='alarm alarm-history capabilities complete help'
# cmds_alarm='create delete list show update'
# cmds_alarm_history='search show'
# cmds_alarm_history_search='-h --help -f --format -c --column --max-width --noindent --quote --query'
#
# 2) Clients with old style bash-completion command which does
# not separate options and commands:
#
# --tenant_id floatingip-delete bgp-peer-delete --default-prefixlen net-create [...]
#
# 3) Swift, slightly different from 2)
