+# auto rebuild 'playdough' app
+#
+# This script can be used to automatically re-create from scratch, a new
+# app named 'playdough' - for sake of testing the cookiecutter template.
+#
+# IMPORTANT: To use this script, place a copy in the root of the
+# cookiecutter template source folder (~/src/cookiecutter-wuttaweb)
+# alongside the cookiecutter.json file.  Name it `newapp.sh` and then
+# modify your copy of the script as needed.  (See TODO comments below.)
+#
+# The script does the following:
+# - remove existing virtualenv and source code
+# - drop and recreate database
+# - make new virtualenv
+# - install cookiecutter
+# - make new source code via cookiecutter
+# - install new app
+# - run web app
