# This script try to autoconfigure the Linux kernel, detecting the
# hardware (devices, ...) and software (protocols, filesystems, ...).
# It uses soft detections: no direct IO access to unknow devices, thus
# it is always safe to run this script and it never hangs, but it cannot
# detect all hardware (mainly some very old hardware).
#
# Report errors, bugs, additions, wishes and comments <cate@debian.org>.
# 
# Usage:
#   General Hints:
#     you don't need super user privileges.
#     you can run this script on a target machine without the need of
#       the kernel sources.
#
# Extra information for the developers:
#   There are a lots of redundance: because user maybe has not already
#     installed the drivers (thus we use smart detection on PCI, USB,..)
#     and not all file methods are usable ('lspci' not installed,
#     '/proc' not mounted or 'dmesg' not usable).
#   We want to check the drivers that system needs, not the drivers
#     actually installed on actual system (in this case you should
#     simply check the 'System.map').
#
# This is a simple bash shell script. It use only the following external
#  program:
#   Req: bash[if,echo,test], grep/egrep, sed, uname, which, cp,mv,rm
#   Opt: dmesg
# and read this files:
#   Opt: /proc/*; /var/log/dmesg; /etc/fstab; linux/drivers/pci/pci.ids
