13# Include all tracked files.
14# When a package uses setuptools-scm as a build-time dependency, it usually
15# expects it to include all scm-tracked files in the built package, by default.
16# This is the official setuptools-scm behavior, documented in
17# https://setuptools-scm.readthedocs.io/en/latest/usage/#file-finders-hook-makes-most-of-manifestin-unnecessary
18# and https://setuptools.pypa.io/en/latest/userguide/datafiles.html.
19# However, while doing a nix build, the source tree doesn't contain SCM data,
20# so it would include only `.py` files by default.
21# We generate a MANIFEST.in automatically that includes all tracked files to
22# emulate this behavior of setuptools-scm.
