What I miss is the support for a prepared vars_wordlets_mods.cgi file and for other files with different languages which I call vars_wordlets_mods_de.cgi or vars_wordlets_mods_it.cgi
The solution in the former devkit (STEP 1, STEP 2, ...) was sufficient but the current one isn't for developers it is a wordlet installation tool for the Who's Online Hack and nearly useless for other hacks.
But I think they will change the "use UBBCGI::Carp qw(fatalsToBrowser set_message);" as well.
