I'm a ruby/haml/sass-beginner. I just installed ruby and rails for windows, haml, and sass (stand alone and plugin for rails).

I know how to convert and **haml** file into a **html** file (and vice versa):

```
haml index.haml > output.html

```

and how to convert a **scss** fiel into a **css** file (and vice versa):

```
sass --watch style.scss:style.css

```

I save more time converting **scss** files because every time I save a **scss** file the corresponding **css** file is automatically updated (i think that's the suppose of the **watch** command) 

but for the haml files, I'm still doing it manually (`haml index.haml > output.html`).

I believe there's other ways to save time converting **haml** and **scss** files.

Any suggestions?
