-//////////////////////////////////////////////////////
-//
-// LuaConsole:
-//
-// Used to parse commands that are being interactively typed
-// in by a user.  The common usage pattern is:
-//
-//    1. Print the prompt suggested by 'get_prompt'.
-//    2. Read a line of text from stdin.
-//    3. Add the line to the LuaConsole using 'add'.
-//    4. Get the command word using get_command.
-//    5. If the command is empty, do nothing.
-//    6. If the command is nonempty, get the args and execute it.
-//
-// The LuaConsole expects you to type a lua command, or one
-// of the following slash-commands:
-//
-//    /quit               - exit the program
-//    /view               - display the nearby tangibles
-//    /menu [tanid]       - display the menu for tangible 
-//    /tick [timevalue]   - advance the simulation clock
-//    /choose [number]    - choose menu item number
-//    /1234               - choose menu item 1234
-//
-// If you type anything else, the LuaConsole will generate a
-// syntax error.  Note that not all of the commands above are
-// supported in all interpreters.
-//
-// Lua commands can be one of the following:
-//
-// <expression>       - invoke "<expression>""
-// = <expression>     - invoke "return <expression>"
-// ? <expression>     - probe "<expression>"
-// ?= <expression>    - probe "return <expression>"
-//
-// Once a command has been typed (or a syntax error has been
-// typed), the LuaConsole will return the command.  The command
-// can be fetched using command(), int_arg(), and str_arg()
-//
