# 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.
