#
# For the Python script interpreter (external to liblldb) to be able to import
# and use the lldb module, there must be two files, lldb.py and _lldb.so, that
# it can find. lldb.py is generated by SWIG at the same time it generates the
# C++ file.  _lldb.so is actually a symlink file that points to the 
# LLDB shared library/framework.
#
# The Python script interpreter needs to be able to automatically find 
# these two files. On Darwin systems it searches in the LLDB.framework, as
# well as in all the normal Python search paths.  On non-Darwin systems
# these files will need to be put someplace where Python will find them.
#
# This shell script creates the _lldb.so symlink in the appropriate place,
# and copies the lldb.py (and embedded_interpreter.py) file to the correct
# directory.
#

# SRC_ROOT is the root of the lldb source tree.
# TARGET_DIR is where the lldb framework/shared library gets put.
# CONFIG_BUILD_DIR is where the build-swig-Python-LLDB.sh  shell script 
#           put the lldb.py file it was generated from running SWIG.
# PYTHON_INSTALL_DIR is where non-Darwin systems want to put the .py and .so
#           files so that Python can find them automatically.
# debug_flag (optional) determines whether or not this script outputs 
#           additional information when running.
