  to RELENG_7:
  
    Add a simple scripting facility to DDB(4), allowing the user to
    define a set of named scripts.  Each script consists of a list of DDB
    commands separated by ";"s that will be executed verbatim.  No higher
    level language constructs, such as branching, are provided for:
    scripts are executed by sequentially injecting commands into the DDB
    input buffer.
  
    Four new commands are present in DDB: "run" to run a specific script,
    "script" to define or print a script, "scripts" to list currently
    defined scripts, and "unscript" to delete a script, modeled on shell
    alias commands.  Scripts may also be manipulated using sysctls in the
    debug.ddb.scripting MIB space, although users will prefer to use the
    soon-to-be-added ddb(8) tool for usability reasons.
  
    Scripts with certain names are automatically executed on various DDB
    events, such as entering the debugger via a panic, a witness error,
    watchdog, breakpoint, sysctl, serial break, etc, allowing customized
    handling.
  
    Remove duplicate $FreeBSD$ that snuck in.
