                        It reads from <code>stdin</code> and writes to

                        <code>stdout</code>.  The reason I wrote this script

                        was that the other HTML minifiers I used were

                        over-optimizing the HTML, causing validation errors.

```

                        I don't use this script any more, as my new design is

                        based on static XHTML5 being served. (Lighttpd can

                        compress static resources but not the output streams

                        from CGI scripts.)

                        This script SHOULD NOT be run on binary files due to

                        The old design was based on fancy Python scripts

                        generating the content.  I made it too automated for

                        too specific types of content.

```
                    </p>
```

                    <p>The objectives for the new design were:</p>

```
                    <ul>
```
```
                        <li>
```

                            Autogenerate the navigation.

                            The only thing I needed to be done automagically.

```
                        </li>
```
```
                        <li>
```

                            Work like a macro expander.

```
                        </li>
```
```
                        <li>
```

                            Generate (mostly) static content,

                            but work for scripts too.

```
                        </li>
```
```
                        <li>
```

                            Be ran from a Makefile.

```
                        </li>
```
```
                    </ul>
```

                    <p>It still has some downsides:</p>

```
                    <ul>
```
```
                        <li>
```

                            A bit terribly implemented.

```
                        </li>
```
```
                        <li>
```

                            A bit limited in certain cases.

```
                        </li>
```
```
                        <li>
```

                            Quite ad-hoc.

```
                        </li>
```
```
                        <li>
```

                            Weird macro syntax.
