  -e, --extensions <list>     The extensions to take into account (defaults to .htm,.html)
  -I, --include <regexp>      Include files and directories that are matched by this regular expression (defaults to all)
  -E, --exclude <regexp>      Exclude files and directories that are matched by this regular expression (defaults to none)

```

#### Install

```console
npm install -g indexifier
```

#### Examples

```console
indexifier ./ --extensions .html,.htm
```
would generate something like this:

```
A
├─┬ B
│ └── c.html
├── d.html
└── e.html
```

There is also an HTML flag that would generate the above output as linked HTML:

```console
indexifier --extensions .html --html .
```

```html
<!-- ... -->
<a href="./">A</a><br/>
├─┬ <a href="./B">B</a><br/>
│ └── <a href="./B/c.html">c.html</a><br/>
├── <a href="./d.html">a.html</a><br/>
└── <a href="./e.html">b.html</a><br/>
<!-- ... -->
```
> The links are always relative to the given directory.
