#~ # openmamba-usbinstall è uno script per la generazione automatica di una chiavetta di boot per openmamba snapshot.
#~ # Se i file necessari sono presenti sul disco fisso verranno utilizzati quelli altrimenti
#~ # scaricherà direttamente la versione attuale dal sito di openmamba.
#~ # se il file iso è presente nella home verrà usato direttamente altrimenti si aprirà un dialogo dove sarà possibile cercarlo.
