""" 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.
