"""
This program takes a Setup file and creates the Makefile-like files
(.dsw and .dsp) needed for simple compilation of Python extension
modules on Windows using DevStudio97.  

Author: David Ascher  [compile_unix modified from Konrad Hinsen's compile.py]
=======

Features:
=========
  - On Unix, does the usual make based on Makefile.pre.in
  - On Windows, creates a .DSW file and as many .DSP files as there
    are modules in the Setup file, and invokes MSVC to build the projects.
    (note: the auto-build facility requires the Python COM extensions)
  - Should work ok for most Setup files without modifications
  - Auto-identifies C and C++ files using wide range of extensions
  - Converts -D, -L, -l tags to approprate Windows versions.
  - Tries to find the location of python15.lib and the Include
    directory (or directories if you have Python before 1.5.1).  Asks
    the user for their locations if can't find it in a few standard places.
  - Builds only one configuration (I *hate* the Debug/Release
    user interface.
  - Builds a project dependency chain based on the sequential order of
    the modules in the Setup file.
  - If a .c file ends in _wrap.c, looks for the corresponding .i file in the
    same directory.  If it finds it, adds the .i file to the project, with
    the commands needed to run SWIG (assuming it can find SWIG).
  - VC-specific options in a Setup file are indicate with the syntax e.g.

      #[VC50]cpp_options.append('/U DOUBLE')
      #[VC50]cfiles.append('_numpy.def')
      #[VC50]swig_options.append('-shadow')

    which can be useful to override defaults set in the Setup file, and 
    to add files to the compilation which are Windows-only (e.g. DEF files
    when building DLLs you want other DLL's to link against).

    Default flags are:
       Defines:  WIN32, NDEBUG, _WINDOWS
       Link: wherever the python15.lib is.
       Include: wherever the Python includes are.

    Useful flags to document in eventual documentation:
       /GR : Enable RTTI --- should it be made default if C++?
    (NOTE: [VC50] tags are used for all versions of VC)

Usage:
======
  On Unix:
    csh> compile.py
    csh> install.py

  On Windows:
    c:\wherever> python compile.py workspacename
    
    If the COM extensions are installed, this should also
    invoke MSDev and build the projects.  To build manually:

    c:\wherever> msdev workspacename.dsw
    [Go to "Build", pull down "Batch Build", do "Build All", exit DevStudio]

    # install by hand -- bins are in pyds/, .py's are in lib/

Todo:
=====
  * write install.py for Windows
  * write test.py for Windows & Unix
  * Figure out how to avoid reSWIGGing every time.

Release History:
================
  0.21 [Mar 10, 1998] Put back Konrad's new compile stuff.  
                      Should work on Unix as well now [da]
  0.2  [Feb 13, 1998] Got rid of unix part -- NumPy specific
                      Released on newsgroup.
  0.1h [Feb 8, 1998]  Made options be lists instead of strings (cleaner Setup
                      files) - backwards compatible thanks to RAddList
  0.1g [Feb 8, 1998]  fixed bug with -L flag
  0.1f [Feb 7, 1998]  Added auto-detect and custom build stuff for shadow
                      files (swig_options, and final 'c' on init routine)
  0.1e [Feb 7, 1998]  Added auto-detect and custom build stuff for SWIG .i files
  0.1d [Feb 6, 1998]  Fixed bug re: detection of -l tags.
  0.1c [Feb 6, 1998]  Limited edition release to P, G, K, H, dek
                      - 'cfiles' moved into self.__dict__
                      - fixed Setup file for NumPy to include .def file
  0.1b [Feb 6, 1998]  Limited edition release to P, G, K, H.
                      - now putting .lib and .exp with .pyd's
  0.1a [Feb 5, 1998]  Limited edition release to P
  0.0  [Feb 4, 1998]  Started work, prompted by discussion with Paul,
                      Guido, Konrad, Harri.
 
Known bugs:
===========
  * It doesn't work on macs.
  * I'd like the .plg files to go in ./tmp (maybe even the .dsp files)

Comments
========
  - There is no way, apparently, to specify C++ compilation on a
    single file, only on all the files in a module (project) at once.
    This is probably not a problem in reality, as most C files go
    through C++ compilers.
