# The HTTP parser, built from source that ships with this package.
#
# It is llhttp — the parser Node uses — behind a binding that used to live in its own
# package, `pyllhttp`. Three things made vendoring it the only arrangement that works:
# the package was archived; every alternative binding with prebuilt wheels fails to load
# in the subinterpreters `cpproxy` runs filters in (they need
# `Py_MOD_PER_INTERPRETER_GIL_SUPPORTED`, which this declares and `httptools` does not);
# and binding the system `libllhttp` through ctypes would mean `pip install firegex`
# assuming a package the user had installed beforehand.
#
# So the C comes with the source, and the release workflow builds wheels for every
# platform it can. Where no wheel matches, pip compiles this — which needs a C toolchain,
# and is the deliberate trade: compiling is a thing pip knows how to do, assuming a
# system library is not.
