IProjekthi izama ukwenza ezi zibe simahla kangangoko, kwiifomati ezihlala ixesha elide, ezivulekileyo ezinokuthi zisetyenziswe phantse kuyo nayiphi na ikhompyuter.

Uninzi olukhutshwayo lungolwimi lwesiNgesi, kodwa imisebenzi emininzi engeyiyo eyesiNgesi iyafumaneka. Kukho iiprojekthi ezininzi ezinxulumeneyo ezibonelela ngomxholo owongezelelweyo, kubandakanywa imisebenzi yengingqi kunye nolwimi oluthile.
