# This scripts provides a default configuration for tmux-backup options and
# key bindings. It is run only once at tmux launch.
#
# Each option and binding can be overridden in your `tmux.conf` by defining
# options like
#
#   set -g @backup-keytable "foobar"
#   set -g @backup-keyswitch "z"
#   set -g @backup-strategy "-s most-recent -n 10"
#
# and bindings like
#
#   bind-key -T foobar l 'tmux-backup catalog list'
#
# You can also entirely ignore this file (not even source it) and define all
# options and bindings in your `tmux.conf`.
