Questions About Managing Embedded Scripts in C++

If the Lua code is literally in the C++ code, then I immediately lose the huge benefit of being able to make changes to the script without having to recompile. I know one solution is to load the code as a string of characters from some outside file and pass that to the function. Or, if I just have the wrong attitude about this, what might be some wise options for loading up the script from some outside source? Right now my only plan is to write it up in a text editor with highlighting (like gedit), save it as a text file and load it up manually from there using the filestream. Plan B is to use pugixml (an xml parser) in a hacky way to read the script in.
Also, feel free to let me know if I'm just confronting this problem completely wrongly. Maybe dealing with a scripting language isn't the right move at all?

It's not quite that complicated. What you want is luaL_dofile. No need to manage the file streams yourself.

Also, the test/example in Luabind is using C++ string for script doesn't mean you must do it.
You can always load the script from anywhere you want, an external file, an XML, what ever, and call Lua API to execute, no matter which script binding engine you are using.
