# This task will destroy all of the Wiki repos
# that the Wiki migration task created. Run this
# to clean up your environment if you experienced
# problems during the original migration. After
# executing this task, you can attempt the original
# migration again.
#
# Notes:
# * This will not affect Wikis that have been created
# as Gollum Wikis only. It will only remove the wikis
# for the repositories that have old Wiki data in the
# dataabase.
# * If you have any repositories already named
# namespace/project.wiki that you do not wish
# to be removed you may want to perform a manual
# cleanup instead.
