The action script language is the same as the command line interface, except
the the leading slash before commands are omitted. Each command is in a new
line and lines starting with a hash mark ('#') are ignored as comments.

The main purpose of the action script language is to serve as the
bootstrap rc file for basic configuration (see run_config.html). Thus the
language does not have variables, branches, loops and can not define
actions/functions. If any of these are needed, the action script should
use the "load" action to execute a script written in a turing complete
language.
