# MAINTAINER notes:

# Cutting a new release:
# 1. Perform a non-anonymous cvs checkout of the BRANCH 
#    you want to cut a release tarball from
# 2. Run "make -f Makefile.maint new-revision"
#    (rsp. "make -f Makefile.maint new-minor").
# 3. Run "make -f Makefile.maint commit"
# 4. Run "make -f Makefile.maint tag"
# 5. Run "make -f Makefine.maint tarball"

# -----------------
# SECURITY: Append a string to tag to avoid accidentially screwing up cvs-tags
# For "hot runs" you will want to use "make -f Makefile.maint TEST_TAG= <command>"
TEST_TAG = -test1
