#
# Makefile to generate release tarballs and other administrative tasks
# provided by Daniel Hermann
#

#
# Generation of a release tarball:
#   - all directories in DISTDIRS are included
#   - all files in DISTFILES are included
#   - all files in KERNELFILES are included as copies in the kernel/
#     subdirectory
#   - a file DISTVERSION is included containing the release version
#
# The generated tarball gets a version determined by DISTVERSION,
# which is either specified as a command line parameter
#      $ make -f Makefile.dist DISTVERSION=1.2.3
# or is set to a "reasonable" default (e.g. 0.0.0.X, see below).
# A file DISTVERSION is generated containing that version.
#
# Note: The DISTVERSION file is also included in KERNELFILES so that it
#       gets copied into the kernel/ subdirectory
#
