I have the latest version of ceon. But using zc1.5, There were some changes that affected zc v1.54 but I did not install them since I am still on zc1.5.

There were javascript files in a directory that I had no idea where to put them, same for css, in a _docs directory. Everything else works nicely, although hyphens in directory names seems to be refused. Underscores work well though.
