"""
This script reads cvc5/src/api/cpp/cvc5_kind.h and generates
.pxd and .pxi files which declare all the cvc5 kinds and
implement a Python wrapper for kinds, respectively. The
default names are kinds.pxd / kinds.pxi, but the name is
configurable from the command line with --kinds-file-prefix.
The script is aware of the '#if 0' pattern and will ignore
kinds declared between '#if 0' and '#endif'. It can also
handle nested '#if 0' pairs.
