OK, time to give up a bit of fun I had planned for Sylpheed-Claws...
ContentLister supports all the trimmings with the [SHELL] hack.
Code:
<?xml version="1.0" encoding="utf-8"?>
<package>
<metadata><dc-metadata><Title>emacs</Title>
<Description/><Date>2006-10-16T08:28:46</Date>
<Format/><Identifier/><Language/><Type/></dc-metadata><y-metadata>
<startpage>run.sh</startpage>
<image>emacs.jpg</image>
<version>000</version></y-metadata></metadata>
</package>
The above is my manifest.xml for the native emacs I use on my iLiad. Not only can you hide everything, you can have a picture/description etc...
Have fun!
