Correspond to Python standard library modules:

stdlib{.h,.cc,_test.cc}
  import fcntl
  import time
  import posix  # forked in pyext/posixmodule.c

Correspond to repo directories:

core{.h,.cc,_test.cc}

osh{.h,.cc,_test.cc}
  from osh import arith_parse
  from osh import bool_stat

pylib{.h,.cc,_test.cc}
  from pylib import os_path
  from pylib import path_stat

pgen2{.h,.cc,_test.cc}
  from pgen2 import parse

qsn{.h,_test.cc}

Corresponds to our Python extensions:

libc{.h,.cc,_test.cc}  # Python module pyext/libc.c

Correspond to individual files:

core_error.h    # corresponds to core/error.py
core_pyerror.h  # corresponds to core/pyerror.py

# These three are separate because there is generated code associated with
# them, like the re2c lexer.

  from frontend import flag_spec

frontend_match{.h,.cc,_test.cc}
  from frontend import match
