-Use this script to upload binary testing data for ITK and related projects.
-
-Binary data, e.g. test input images, are not stored in Git because they
-will bloat a Git repository's size.
-
-
-To use the script:
-
-1. Sign up for an account at https://data.kitware.com
-2. Place the binary file at the desired location in the Git repository.
-3. Run this script, and pass in the binary file(s) as arguments to script.
-4. In test/CMakeLists.txt, use the itk_add_test macro and reference the file
-   path with \`DATA\` and braces, e.g.: DATA{<Relative/Path/To/Source/Tree/File>}.
-5. Re-build ITK, and the testing data will be downloaded into the build tree.
-
-
-If the Git `girder.api-key` config or `GIRDER_API_KEY` environmental variable
-is not set, a prompt will appear for your username and password. The API key
-can be created in the data.kitware.com user account web browser interface.
-
-The script will authenticate to data.kitware.com, upload the file to your
-user account's Public folder, and create a *.sha512 CMake ExternalData
-content link file. To specify a different folder, use the --folder flag.
-After the content link has been created, add the *.sha512 file to your
-git commit. The binary file will be removed from the source tree following
-upload.
