I need an environment similar to, but not identical to LyX-Code

[Steve Litt]

I need an environment similar to, but not identical to the LyX-Code
environment. Specifically, I need the page margins to be the same as
regular text, and I'd also like a smaller font.

So I figured I'd find the LaTeX definition of LyX-Code and work from
there, possibly using CopyStyle. But I've searched for 1/2 hour and
cannot find the TeX definition of the latexname part of LyX-Code, nor
can I find the LyX user interface part of LyX-Code.

So where can I find the definition of LyX-Code?
