Updated README for 0.5 release.

Usage

-----

Just call it from command line with output directory and a list of

JavaScript files:

Just call it from command line with output directory and a directory

containing your JavaScript files:

    $ jsduck --verbose --output some/dir  your/project/*.js

    $ jsduck --verbose --output some/dir  your/project/js

To specify a lot of files you should probably create a script that

generates a file list and passes it through `xargs` to `jsduck`.

The `--verbose` flag creates a lot of output, but at least you will

see that something is happening.

For example to generate documentation for ExtJS:

You pass in both directories and JavaScript files.  For example to

generate docs for ExtJS 3, the simplest way is the following:

    $ find ext-3.3.1/src/ -name '*.js' | egrep -v 'locale/|test/|adapter/' | xargs jsduck -v -o output/

    $ jsduck -v -o output/ ext-3.3.1/src/

The `--verbose` flag creates a lot of output, but at least you will

see that something is happening.

But this will give you a bunch of warnings, so you should better

create a script that takes just the files really needed and passes

them through `xargs` to `jsduck`:

    $ find ext-3.3.1/src/ -name '*.js' | egrep -v 'locale/|test/|adapter/' | xargs jsduck -v -o output/

Here's how the resulting documentation will look (ExtJS 3.3.1):

* [JsDuck generated documentation](http://triin.net/temp/jsduck/)

* [Official ExtJS documentation](http://dev.sencha.com/deploy/dev/docs/) (for comparison)

Here's the same for ExtJS 4 Preview 2:

Here's the same for ExtJS 4 Preview 5:

* [JsDuck generated documentation](http://triin.net/temp/jsduck4/)

* [Official ExtJS documentation](http://dev.sencha.com/deploy/ext-4.0-pr2/docs/) (for comparison)

Documentation

Missing features and TODO

-------------------------

* Search, not just searching from official ExtJS documentation.

* Support for custom @tags. Ext-doc supports this, I personally have

  never used this feature, so I'm thinking it's not really needed.
