I'm sorry, but I'm not going to be able to apply this.  We have to think
about the readability of the plain-text documentation *first*, and LeTeX
source scores poorly on that metric.

So, just for example:

> +  \text{capacity(cpu)} = \text{work\_per\_hz(cpu)} \times \text{max\_freq(cpu)}

The document is not improved by this kind of change, even if the
rendered version is prettier.

I do appreciate your effort to make the documentation better, but please
focus on the readability of the original docs and not just the rendered
version.

Thanks,

jon
