And also an icons.css with all the necessary CSS classes for this sprite:

.sprite-icons-zoom_out{ background:url('icons.png'); top:0; left:0; no-repeat;}
.sprite-icons-zoom_in{ background:url('icons.png'); top:0; left:-16; no-repeat;}

Is your company using glue?

We are creating a list of companies using glue in production. If your company use glue, please send me an email or send me a message to @jorgebastida . I would really appreciate it.

We need your help

There are several features that glue users would love to have... but they require a substancial amount of work and dedication, so we are looking for feature-sponsors! If you want to lead the development/testing of any of the following features, please contact Jorge Bastida.

Here you have some examples:

• Windows support (I'm not a Windows user, glue needs somebody who care about how glue works on Windows and write down some installation instructions).
• Cocos2d Format (Already exists, but we need somebody to give it some love).
• New Formats (After 0.9, glue is ready to accept new output formats - If you want to create a new format, contact me).
• Binary packaging for OSX and Windows (For some users it would be really cool if they were able to download an already packaged binary version).
• Python 3 support.
