              [-2]  [-3]  [--3str]  [-+]  [-a]  [--annotate-fullc]  [-x PATTERN] [-b] [-i] [--timeit CODESTRING]
              [--setup CODESTRING] [-j N] [-f] [-q] [--lenient] [-k] [--no-docstrings] [-M] [sources ...]

   positional arguments:
              sources

   options:
       -h, --help
              show this help message and exit

       -X, --directive NAME=VALUE,...
              set a compiler directive

       -E, --compile-time-env NAME=VALUE,...
              set a compile time environment variable

       -s, --option NAME=VALUE
              set a cythonize option

       -2     use Python 2 syntax mode by default

       -3     use Python 3 syntax mode by default

       --3str use Python 3 syntax mode by default (deprecated alias for -3)

       -+, --cplus
              Compile as C++ rather than C

       -a, --annotate
              Produce a colorized HTML version of the source.

       --annotate-fullc
              Produce a colorized HTML version of the source which includes entire generated C/C++-code.

       -x, --exclude PATTERN
              exclude certain file patterns from the compilation

       -b, --build
              build extension modules using distutils/setuptools

       -i, --inplace
              build extension modules in place using distutils/setuptools (implies -b)

       --timeit CODESTRING
              build in place, then compile+run CODESTRING as benchmark in first module's namespace (implies -i)

       --setup CODESTRING
              use CODESTRING as pre-benchmark setup code for --bench

       -j, --parallel N
              run builds in N parallel jobs (default: 6)

       -f, --force
              force recompilation

       -q, --quiet
              be less verbose during compilation

       --lenient
              increase Python compatibility by ignoring some compile time errors

       -k, --keep-going
              compile as much as possible, ignore compilation failures

       --no-docstrings
              strip docstrings

       -M, --depfile
              produce depfiles for the sources

   Environment variables:
              CYTHON_FORCE_REGEN: if set to 1, forces cythonize to regenerate the output files regardless

              of modification times and changes.

              CYTHON_CACHE_DIR: the base directory containing Cython's caches.  Environment  variables  accepted
              by     setuptools     are    supported    to    configure    the    C    compiler    and    build:
