The emk.js may need to do some async operations before it knows what the build config should be. Would be great to allow the module.exports value to return a Promise or async function that resolves once config is ready.

Would be useful for running test cases with watch flag.

In addition to using an absolute/relative file path, would be nice to be able to supply a URL for dependency strings that checks the Last-Modified HTTP header of a resource against the build target.

With all the verbose console output, it would be nice to clarify to the user that certain stderr messages are not errors but instead just warnings, etc.

E.g.,

link: {
   run: /* syntax: bash */ `
      npm link
   `,
   // before printing to error channel from stderr
   stderr: {
      // change tag to 'warn' for lines that meet criteria..
      warn: [
         // for outputs that match this pattern
         /^npm notice/,
      ],
   },
}

If a build task fails, it should delete the file by default so that the mtime of the output does not cause the build system to skip the task next time it is run, i.e., mistaking the fact that the previous build failed.
