# PCIDEV - PCI device drivers scanner version 0.2

# usage :
# pcidev [-vnm] [path to modules.pcimap]
# example :
# pcidev /lib/modules/`uname -r`/modules.pcimap
#
# This program lists all pci devices, displays their IDs
# and the names of the driver attached to each device, when
# available, or "##none##'. If an argument is passed, it will
# be interpreted as the path to a modules.pcimap file. In this
# case, the list of all possible modules for each device is
# appended at the end of the line.
# If the "-n" argument is given, only modules that seem not to
# have already been loaded will be. If the "-m" argument is given,
# those modules will be loaded through modprobe (verbosely if "-v"
# is specified).
