import { type StderrHandler } from "https://deno.land/x/proc@0.20.15/mod3.ts";
Optionally handle lines of stderr (passed as arrays of lines as available), and also
optionally return a value that is passed to your custom ErrorHandler. This function
may not throw an error. If you wish to throw an error based on stderr data, the
ErrorHandler function is where you do that.
