[xwiki-devs] CSS content placeholder when customizing a skin

Hello Xwiki devs, I want to customize the COLIBRI skin.. for the very beginning just the colibry.css file. Basically I've just added a few lines to the original file. I don't want to paste into the 'style' text area ( http://localhost:8080/xwiki/bin/edit/XWiki/RtSkin?editor=object) the whole content of the css file because like I said it has minor additions not modifications. Furthermore when a modification is done to the default colibry.css file, mine's will be deprecated! So do you happen to know if there is a placeholder for the default colibry.css file? To make myself clear, I've painted a pictogram : Style________________________________ | %{placeholder for original Colibry.css}% | | AND here are my additions | |____________________________________| -- ing.
