rockbox/utils/newparser/skin_render.c
Jonathan Gordon b4a9564790 Add my new parser playground to svn.
Currently it can load a skin, and walk the parse tree and output the tags as required. It always chooses the first value for a conditional and subline, but a good working start
there seems to be a error in the new parser if ROCKBOX is defined... need to fix that
