+#### options
+
+ - **no-prelude**: Boolean value that toggles `--no-prelude`
+  - Do not include the Prelude in the generated Javascript.
+ - **no-opts**: Boolean value that toggles `--no-opts`
+  - Disable all optimizations.
+ - **no-magic-do**: Boolean value that toggles `--no-magic-do`
+  - Turn off optimizations which inline calls to >>= for the Eff monad.
+ - **no-tco**: Boolean value that toggles `--no-tco`
+  - Turn off tail-call elimination.
+ - **runtime-type-checks**: Boolean value that toggles `--runtime-type-checks`
+  - Generate simple runtime type checks for function arguments with simple types.
+ - **verbose-errors**: Boolean value that toggles `--verbose-errors`
+  - Generate verbose error messages.
+ - **output**: String value that sets `--output=<string>`
+  - Write the generated Javascript to the specified file.
+
+## Example
+
+```js
+var path = require('path');
+
+module.exports = {
+  entry: './src/test',
+  output: {
+    path: path.join(__dirname, 'dist'),
+    filename: 'app.js'
+  },
+  module: {
+    loaders: [{
+      test: /\.purs$/,
+      loader: 'purs-loader?no-prelude&output=output'
