I love using Jan Kovařík's Glyphicons in my web app. So much so that I've created a set of helpers to allow me to say things like

<%= glyphicon :remove %>

and

<%= link_to_glyphicon :remove, … %>

Here's the code. You'll find:

• A Rake task to create the required data structures.
• The output of that Rake task (glyphicons.rb).
• And finally the helper that allows me to say.

Feel free to use it. Enjoy!
