+# This script is an attempt to automate the Lift release process
+#
+# From Indrajit, the steps on each module (superbuild, framework, examples) are:
+#
+# 1. git checkout -b <version>
+# 2. ./liftsh 'set project.version <version>'
+# 3. Edit project/plugins/Plugins.scala to change the version of lift-sbt
+# 4. git commit -v -a -m "Prepare for <version>"
+# 5. git push origin <version>
+# 6. git tag <version>-release
+# 7. git push origin <version>-release
+# 8. LIFTSH_OPTS="-Dpublish.remote=true -Dsbt.log.noformat=true" ./liftsh clean-cache clean-plugins reload +clean-lib +update +clean +publish
+# 9. Wait for happiness
