Parameterize the shell scripts for creating and copying the python and

other script files around, so they can be run from outside Xcode.  Also,
check the current OS, and only try to use the framework structure stuff on
Darwin systems.

 # finish-swig-Python.sh
 #
 # For the Python script interpreter (external to liblldb) to be able to import
-# and use the lldb module, there must be a "_lldb.so" in the framework 
-# resources directory. Here we make a symlink called "_lldb.so" that just
-# points to the executable in the LLDB.framework and copy over the needed
-# .py files.
+# 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.
