I untarred the source files in /usr/share/icewm/themes just like other themes I installed but these don't show up in the themes submenu folder. For example:
http://themes.freshmeat.net/projects/incel/ I can't get this one to show up or the IceCrack theme
Some others showed up immediately in the list but these don't. Do I have to do anything special or are they broken (doesn't seem to be the case to me)
