<h2>Excluding the lua bytecode compiler</h2>
By default, the compiler is not included so as to minimize footprint.
By default, the compiler is included whenever <em>standardGlobals()</em> or <em>debugGlobals()</em> are called.
Without a compiler, files can still be executed, but they must be compiled elsewhere beforehand.
The "luac" utility is provided in the jse jar for this purpose, or a standard lua compiler can be used.

To include the lua-to-lua-bytecode compiler, include the following sometime before lua source files are loaded:
To exclude the lua-to-lua-bytecode compiler, do not call

To omit the compiler, omit this line from your startup code.
