# DESCRIPTION: an interactive wrapper to Debian's "make-kpkg"
# to build a custom kernel package using
# Distributed CC (distcc) and ccache if available.
#
# USAGE: cd to /usr/src/linux (or the linux source tree)
# and then call:
#
# make-kpkg.sh N1 N2
#
# where N1 is the number or string appended to the kernel
# (01 or 02, or 03..., etc...)
# and N2 is the revision of this kernel: 1.0, 1.1 ...
# e.g.:
#
# make-kpkg.sh -desktop 1.0
# TIPS:
# * setup a $HOME/.make-kpkg.rc with the variables found in this
# script (see below) to override them
# * N2 is optional. It defaults to 1.0
#
# NOTES:
# * If your modules are in /usr/src/modules, then your kernel
# is in /usr/src/linux. In other words, "modules" dir is parallel
# to your "linux" source directory. Same applies to "kernel-patches"
# * For distcc/ccache to work, the script assumes that
# a symlink /usr/local/bin/gcc -> /usr/bin/ccache exists
# * If distributed cc (distcc) is installed, then we will distribute
# our compilation to the hosts found in: ~/.distcc/hosts
# * If we also have ccache installed, then we arrange the commands
# so that we can use both ccache and distcc.
# Make sure that $CCACHE_DIR is setup correctly (man ccache)
# LICENSE: GPL (http://www.gnu.org/licenses/gpl.txt)
#
# CHANGES:
# 2006-03-25 07:45 EST - applied Antonio Ospite patch which allows newer
# versions of make-kpkg to do "clean" and "modules_clean"
#
