-$FUNCTION kill_builtin
-$SHORT_DOC kill [-s sigspec | -n signum | -sigspec] [pid | job]... or kill -l [sigspec]
-$_ "Send the processes named by PID (or JOB) the signal SIGSPEC. If"
-$_ "SIGSPEC is not present, then SIGTERM is assumed. An argument of `-l'"
-$_ "lists the signal names; if arguments follow `-l' they are assumed to"
-$_ "be signal numbers for which names should be listed. Kill is a shell"
-$_ "builtin for two reasons: it allows job IDs to be used instead of"
-$_ "process IDs, and, if you have reached the limit on processes that"
-$_ "you can create, you don't have to start a process to kill another one."
