attrs.putBoolean("admin", false);
return attrs;
}
// This will use the User class (Adming would have been guessed)
}, new Definition(User.class, "admin") {
@Override
public Bundle set(Bundle attrs) {
attrs.putString("name", "Admin");
attrs.putBoolean("admin", true);
return attrs;
}
});
```

Contribution

Just fork & edit & send pull-request on GitHub!

####Policy

1. Official Website over GitHub Repository for links.
2. Should put codes which reflects the library.
3. For UI libraries, put demonstorations (AniGIF, PNG, Movies).

And I am considering to ...

1. Put reference links for each libraries.
2. Separate pages for each categories.
3. Separate UI categories.
