As we give a list of zippers on failure, the following might be better:

         local done = false

         for i=1,#zippers do
             local zipper = zippers[i]
             if 
os.execute(format(zipper.uncompressed,epubfile,"mimetype")) then
                 os.execute(format(zipper.compressed,epubfile,"META-INF"))
                 os.execute(format(zipper.compressed,epubfile,"OPS"))
                 done = zipper.name
                 break
             end
         end

         lfs.chdir("..")

         if done then
             application.report("epub archive made using %s: 
%s",done,file.join(epubpath,epubfile))
         else
             local list = { }
             for i=1,#zippers do
                 list[#list+1] = zipper.name
             end
             application.report("no epub archive made, install one of: 
%s",concat(list," "))
         end

(I will look into the os.execute later .. remind me if needed.)
