| 15 | This module provides support for building a new version of the |
| 16 | Python executable. This will be necessary on systems that do |
| 17 | not support shared libraries and may be necessary with C++ |
| 18 | extensions. This file contains everything you need to build |
| 19 | a new version of Python from include files and libraries normally |
| 20 | installed with the Python language. |
| 21 | |
| 22 | This module will automatically grab all of the Python modules |
| 23 | present in your current Python executable (including any special |
| 24 | purpose modules you have enabled such as Tkinter). Thus, you |
| 25 | may need to provide additional link libraries when compiling. |
| 26 | |
| 27 | This library file only works with Python 1.5. A version |
| 28 | compatible with Python 1.4 is available as embed14.i and |
| 29 | a Python1.3 version is available as embed13.i. As far as |
| 30 | I know, this module is C++ safe. |
