-Set `pscPackage` query parameter to `true` to enable `psc-package` support. The `psc-package`-supplied source paths
-will be appended to `src` parameter.
+When the `watch` option is set to `true`, psc errors are appended to
+webpack's compilation instance errors array and not passed back as an
+error to the loader's callback. This may result in the error not being
+reported by webpack. To display errors, the following plugin may be added
+to the webpack config.
+
+```javascript
+const webpackConfig = {
+ // ...
+ plugins: [
+ function(){
+ this.plugin('done', function(stats){
+ process.stderr.write(stats.toString('errors-only'));
+ });
+ }
+ ]
+ // ...
+}
+```
