sorry to be rude and speak english, but my german is not that great

I would like some information regarding how to write a plugin on the dbox ; all I would like to do as a first step is a plugin that deletes a file (ie services.xml), copy a files from a location to another one and reboot the box. Anyone's got a link to a faq on how to write/compile stuff for dbox as I can't find anything. (even german links will do)
Many thanks in advance
