# The Install simply copies the "clamassassin" script file into /usr/bin, then changes its attributes to 555.
# L'Installazione si limita a copiare lo script-file "clamassassin" in /usr/bin ed a cambiarne i permessi in 555. 

# --disable-signature-version: if enabled we must change the "/usr/share/clamav" permissions from 770 to 771 and
# the ones of the "virus definitions files" included in order to give them read access to "others". 
# --disable-signature-version: se abilitata implica il cambiamento dei permessi della dir. "/usr/share/clamav" da
# 770 a 771 e quello dei files di definizione virus in essa contenuti per permetterne la lettura ad "others".
