Setup for creating PIP packages for HFST Python bindings.
Before running setup, recursively copy directories 'libhfst/src'
and 'back-ends' from HFST C++ source code under the directory where
setup is run (on linux and OS X with copy-files.sh and on windows with
copy-files-win.sh). Make sure that the following C++ files
from 'libhfst/src/parsers' have been generated from flex/yacc files
before copying (on linux and OS X by running 'make' and on windows
with 'compile-parsers-win.sh' located in 'libhfst/src/parsers'):
lexc-lexer.cc pmatch_lex.cc xfst-lexer.cc xre_lex.cc sfst-scanner.cc
lexc-parser.cc pmatch_parse.cc xfst-parser.cc xre_parse.cc sfst-compiler.cc
lexc-parser.hh pmatch_parse.hh xfst-parser.hh xre_parse.hh sfst-compiler.hh
Compiling the extensions requires python, swig and a C++ compiler,
all located on a directory listed on system PATH. On linux and OS X,
readline and getline must be available.
The setup script has been tested on linux with gcc 5.4.0, swig 3.0.12 and
python 3.5 and on windows with swig 3.0.5 and msvc 10.0 (with python 3.4)
and msvc 14.0 (with python 3.5 and 3.6).
