# Release checklist:
#  1. Check that the tree has what you want
#
#  2. Update VERSION (above) and debian/changelog
#     but DO NOT COMMIT
#
#  3. Run
#       ./configure
#       make dist
#     and check that the resulting tarball looks OK.
#     Eg, untar it and build it, or have it reviewed.
#
#  3. Commit the updates to VERSION (above) and debian/changelog
#
#  4. git-tag -s v$(VERSION)
#
#  5. git-push origin
#
#  6. Run, again,
#       make dist
#
#  7. gpg --detach-sign ../secnet-$(VERSION).tar.gz
#
#  8. rsync -v ../secnet-$VERSION.tar.gz* \
#        chiark:/home/ianmdlvl/public-html/secnet/download/
#
#  9. On chiark:
#       tar zxf ~ianmdlvl/public-html/secnet/download/secnet-$(VERSION).tar.gz
#       cd secnet-$(VERSION)
#       debian/rules build

#       mv ../secnet_0.1.18.1-1_i386.deb ~/public-html/secnet/download/
#
#  10. On chiark as user secnet:
#       cd ~secnet/
#       rsync ~ianmdlvl/public-html/secnet/download/secnet* .
#
#  11. write and post a release announcement
