# This is a generic EVMS build script for Gnu-based systems under
# BASH.  Only thing you'd have to fiddle with is the
# "KERNEL_EXTRAVERSION=", creating a "kernel-2.4.24-i686-evms.config"
# for your system, doing the "make modules_install", and installing the
# evms utilities..  Hope it helps someone.  (Conforms to evms docs at
# http://evms.sourceforge.net/install/ which are excellent.)
