# The Debian source tarball is created by combining the upstream source and data tarballs
# For ITK 5.2.1 this was done manually:
#
# 1. Download manually:
#    a. https://github.com/InsightSoftwareConsortium/ITK/releases/download/v5.2.1/InsightToolkit-5.2.1.tar.gz
#    b. https://github.com/InsightSoftwareConsortium/ITK/releases/download/v5.2.1/InsightData-5.2.1.tar.gz
#
# 2. Extract in "tarballs", create new merged source tarball:
#    mv ~/Downloads/Insight* .
#    tar xzf InsightToolkit-5.2.1.tar.gz
#    tar xzf InsightData-5.2.1.tar.gz
#    tar --xz -cf insighttoolkit5_5.2.1.orig.tar.xz InsightToolkit-5.2.1
#
# 3. Import into GIT
#    gbp import-orig --pristine-tar ../tarballs/insighttoolkit5_5.2.1.orig.tar.xz
