# clean-clone sdist that would otherwise be ~350MB.

# The exclude/gitignore walk above also hides these git-tracked files as collateral damage from
# vendored .gitignore rules elsewhere in the tree (astc-encoder's own `.gitignore` has a bare
# `/*.txt` that matches its CMakeLists.txt/LICENSE.txt; trimming KTX-Software/tests/ above removes
# tests/CMakeLists.txt, which KTX-Software's top-level CMakeLists.txt add_subdirectory()s
# unconditionally). Without these, sdist configure fails even on an unmodified sdist with none of
# the excludes above applied -- this is a pre-existing packaging bug, not something the trimming
# introduces. sdist.include is checked before exclude/gitignore filtering, so listing them here
# forces them back in.
