# 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 -m "secnet $VERSION" -s v$VERSION
#
#  5. git-push origin v$VERSION v${VERSION}~0:master
#
#  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
#       fakeroot debian/rules binary
#       mv ../secnet_${VERSION}_i386.deb ~ianmdlvl/public-html/secnet/download/
#
#  10. On chiark as user secnet:
#       cd ~secnet/public-html/release/
#       mkdir $VERSION
#       cd $VERSION
#       ln -s /home/ianmdlvl/public-html/secnet/download/secnet?$VERSION* .
#
#  11. write and post a release announcement
