# this makefile will build the tarball and setup the links in
# your ~/rpm directory to build the mandrake RPMs. This makefile
# is based on the redhat one - but it is a bit different. it wont
# create an rpm directory structure for you, nor will it create the
# .rpmmacros etc.. files. Set these up based on the RPM howto
# that mandrake publishes:
#
# http://www.linux-mandrake.com/howtos/mdk-rpm/
#
# You should try the `check_release' target before you make all to make
# sure all the version numbers were groked correctly.
#
# This makefile doesn't copy the source tree to make a tarball, it 
# will create a symlink in your $TMPDIR and tar up your source tree
# in place. This makefile uses the output tarball name as a dependancy,
# so it wont constantly regenerate it unless your repository version
# number changes.
#
# you may append a definition for MDK_RELEASE on your make line to
# change the number that comes before mdk. i.e., make MDK_RELEASE=2
# will make a ...3410.2mdk or similair.
