(more info about GML on GraffitiMarkupLanguage.com)

The main idea behind this library is to provide a maximum help
in the parsing and manipulation of gml elements and allow people
to focus on the drawing side by implementing their own way to draw.

You are invited to contribute and implement your own custom drawers.
You can post your realizations to:
Flickr group: http://flickr.com/groups/gml4u
Vimeo group: http://vimeo.com/groups/gml4u
Vimeo channel: http://vimeo.com/channels/gml4u

If you want to share your custom drawer’s code, please get in touch with me
and I’ll compile the submissions in a gml4u.drawers package.

For info, stay tuned to @gml4u on Twitter.
