# NOTE, vBulletin is setup to 'override' the ':'.  USUALLY, it is good to use something 
# outside of the ASCII values from 0x20 to 0x7F.  0x1F is a 'good' choice, but it will
# cause john.conf to have a 'non-normal' ASCII char.  Thus for this 'simple' example, I 
# have used the ';' character.  NOTE this would have the same 'problems' as the ':' character
# if used for real, since ; is also a valid character within the salt of vBulletin.
# NOTE to run, you MUST use the command line switch:   -field-separator-char=;
