""" 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.
