# Apparently upstream requires that the compiled executable will know the
# commit hash and the date of the commit. This information is also presented
# in the output of `pdfcpu version` which we use as a sanity check in the
# installCheckPhase. This was discussed upstream in:
#
# - https://github.com/pdfcpu/pdfcpu/issues/751
# - https://github.com/pdfcpu/pdfcpu/pull/752
#
# The trick used here is to write that information into files in `src`'s
# `$out`, and then read them into the `ldflags`. We also delete the `.git`
# directories in `src`'s $out afterwards, imitating what's done if
# `leaveDotGit = false;` See also:
# https://github.com/NixOS/nixpkgs/issues/8567
