Should lh_build produce an iso?

[lists at tomgeorge.info (Thomas H. George)]

I haven't quite got the hang of it.  make-live is depreciated but one 
reference claimed the same options work with lh_build.  I tried 
lh_config followed by lh_build -p gnome-desktop but the option -p is 
unknown.  lh_build gnome-desktop runs, does a great deal of work and 
seems to exit normally but I cannot find any newly created iso file.
