""" Copies the build output of a custom python interpreter to a directory structure that mirrors that of an official Python distribution. -------------------------------------------------------------------------- File: install_custom_python.py Overview: Most users build LLDB by linking against the standard Python distribution installed on their system. Occasionally a user may want to build their own version of Python, and on platforms such as Windows this is a hard requirement. This script will take the build output of a custom interpreter and install it into a canonical structure that mirrors that of an official Python distribution, thus allowing PYTHONHOME to be set appropriately. Gotchas: None.
