# biosgrabber.pl, a new script to harvest BIOS version numbers (for BIOSen that
# print their version number to the serial console) from cature logs. It prints
# out SQL commands to update the database stdout. You'll want to change the
# parseVersion function, especially the regular expression in it, to match the
# BIOS version string printed by your machines' BIOS
