""" Post process SWIG Bridge wrapper code Python script for Windows/LINUX/OSX platform
--------------------------------------------------------------------------
File: finishSwigWrapperClasses.py
Overview: Python script(s) to finish off the SWIG Python C++ Script
Bridge wrapper code on the Windows/LINUX/OSX platform.
The Python scripts are equivalent to the shell script (.sh)
files.
We use SWIG to create a C++ file containing the appropriate
wrapper classes and functions for each scripting language,
before liblldb is built (thus the C++ file can be compiled
into liblldb. In some cases, additional work may need to be
done after liblldb has been compiled, to make the scripting
language stuff fully functional. Any such post-processing
is handled through the Python scripts called here.
Gotchas: None.
Copyright: None.
