# Very simple session manager for uzbl-browser.
# To use, add a line like 'bind quit = spawn @scripts_dir/session.sh endsession'
# to your config.
# To restore the session, run this script with the argument "launch". An
# instance of uzbl-browser will be launched for each stored url.
#
# When called with "endsession" as the argument, it will backup
# $UZBL_SESSION_FILE, look for fifos in $UZBL_FIFO_DIR and instruct each of them
# to store its current url in $UZBL_SESSION_FILE and terminate.
#
# "endinstance" is used internally and doesn't need to be called manually.
