Good question. Well no, the libjte in jigit is the same you've 
downloaded, however it is
a debian-cd script [1] which post-process .jigdo files in order to add 
additional info
(see input parameters of jigdo_cleanup). These data are all known prior 
to ISO/jigdo creation
and are indeed better to be passed via option parameters to the 
producer itself
(xorriso, resp. libjte), which is not implemented yet of course. But 
this is a low-priority goal, isn't it?
