-Some of the example files use the `inspect` Lua library to show debugging
-output. It is not needed for the actual functionality of the examples, so if
-you don't have the library, you can remove all uses of `inspect` and the
-scripts should still work.

-The library is available from [the

-can install the `lua-inspect` package.
