import { type StderrHandler } from "https://deno.land/x/proc@0.20.16/mod3.ts";
Optionally handle lines of stderr (passed as text lines), and also
optionally return a value that is passed to your custom ErrorHandler. You are
not allowed to throw an error from this function. If you wish to throw an error
based on stderr data, the ErrorHandler function is where you do that.
