# Force LF line endings on every text source. Without this, a Windows
# clone with `core.autocrlf=true` (the Git for Windows default) checks
# out shell scripts and Makefiles as CRLF. WSL bash then trips on the
# `\r` bytes ("set: pipefail: invalid option name") and the build/cross
# toolchain script bombs in the first 20 lines. Linux/macOS users are
# unaffected -- they were already getting LF.

# Vendored third-party code: the Doom engine port under apps/doom/ is
# Chocolate-Doom-derived code (GPL-2.0) imported via doomgeneric. Marking
# it `linguist-vendored` keeps GitHub from counting those ~60k lines toward
# the StinkOS language stats AND suppresses the secondary licence detection
# that would otherwise paint the repo header with a "GPL-2.0 also" tag.
# The licence text is still distributed at apps/doom/COPYING so we remain
# compliant with the GPL-2.0 obligation; we just don't double-advertise it
# on the front page.
